the square root of 16 is 4 is a start
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
and half of 10 is 5, giving you \[\sqrt{16g^{10}}=4g^5\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
yes you got it

@satellite73 ?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
man they really reach for these word problems, don't they?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
perimeter is \[\sqrt{13}+\sqrt{13}+7\sqrt{13}+7\sqrt{13}\] add to get \(16\sqrt{13}\)

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
\(\sqrt{20}+\sqrt{40}\sqrt{5}\) you have to write the first two in simplest radical form do you know how to do that?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
ok look to factor the number inside the radical as a perfect square, times something for example \(20=4\times 5\) and \(4\) is a square you get \[\sqrt{20}=\sqrt{4\times 5}=\sqrt{4}\sqrt{5}=2\sqrt{5}\] you don't need to write all those steps, that is only my explanation
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
see if you can try that with \(\sqrt{45}\)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
if you get stuck let me know, but it is not too bad for \(45\)
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
\[\sqrt{45}=\sqrt{9x5}=\sqrt{9}\sqrt{5}\]?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
so finish with \(\sqrt{9}\sqrt{5}=3\sqrt{5}\)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
now the whole problem is a matter of combining like terms for \[2\sqrt{5}+3\sqrt{5}\sqrt{5}\] which is identical to \[2+31\] really, just stick a \(\sqrt{5}\) next to the answer
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
\[4\sqrt{5}\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
got it
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
how about the last one \[9^{\frac{1}{3}}\times 81^{\frac{1}{3}}\]? you got that?
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
I got 9 for the last one
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
you win

tmybby Group TitleBest ResponseYou've already chosen the best response.1
could you still help me?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
sure why not?

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
for a rational exponent, the power is the numerator and the root is the denominator
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
your exponent will be negative, since the variable is in the denominator
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
oh okay so it's C?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
should get \[\large 8x^{\frac{15}{7}}\] yes, C
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
for the second one i can't really read the exponents
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
is the exponent in the numerator a 3 or an 8 ?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
oh, then \(\sqrt[3]{x^3}=x\) and you have \[\frac{x}{\sqrt[5]{x^2}}\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
you can write this as \[\frac{x}{x^{\frac{2}{5}}}\] and then subtract the exponents
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
\[\large x^{1\frac{2}{5}}=x^{\frac{3}{5}}\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
that it?
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
i have 3 more problems /:
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
i am ready if you are
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
okay hold on... :)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
just like the previous one, multiply top and bottom by \(\sqrt{2}+\sqrt{5}\)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
\[\frac{\sqrt{2}+\sqrt{5}}{\sqrt2\sqrt5}\times\frac{\sqrt{2}+\sqrt{5}}{\sqrt2+\sqrt5} \]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
\[\frac{2+2\sqrt{10}+5}{25}\] \[\frac{7+2\sqrt{10}}{3}\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
any ideas for this one?
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
one think should be ok, that \[\large (a^{3})^{\frac{2}{3}}=a^{3\times \frac{2}{3}}=a^2\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
for \(8^{\frac{2}{3}}\) you have an exponent with a a) three in the deminator b) 2 in the numerator and c) a minus sign they mean a) take the cube root b) square c) take the reciprocal
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
therefore you get the cubed root of 8 is 2 2 squared is 4 the reciprocal of 4 is \(\frac{1}{4}\)
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
final answer is therefor \[\frac{x^2}{4}\]
 one year ago

tmybby Group TitleBest ResponseYou've already chosen the best response.1
okay! One more...
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
that is an easier one multiply top and bottom by \(\sqrt3\) to get \[\frac{5\sqrt{3}+\sqrt{6}}{3}\]
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.2
typo there ! \[\frac{5\sqrt{3}\sqrt{6}}{3}\]
 one year ago
