Minus the exponents then add the coefficients

Is this some form of alien math?

I've never seen a problem like that in my life, but try what I said.

All yours Jamie

the swiggle thing is supposed to be a three

i got 22a to the power of 1/6
asnaseer
  • asnaseer
is this your question?\[5a^{\frac{2}{3}}\times\sqrt{a^{\frac{3}{2}}}\]
anonymous
  • anonymous
no square root it is a 4
asnaseer
  • asnaseer
so like this?\[5a^{\frac{2}{3}}\times4a^{\frac{3}{2}}\]
anonymous
  • anonymous
ya
anonymous
  • anonymous
i couldnt figure out how to do that on equation
asnaseer
  • asnaseer
ok, so first of all where did you get 22 from in your answer?
asnaseer
  • asnaseer
you said up there "i got 22a to the power of 1/6"
anonymous
  • anonymous
well i gto 20a to the power of 26 over 12
asnaseer
  • asnaseer
and how did you arrive at 26 over 12?
anonymous
  • anonymous
i made the exponents have common denoms
anonymous
  • anonymous
of 12
asnaseer
  • asnaseer
remember that:\[a^n\times a^m=a^{n+m}\]
asnaseer
  • asnaseer
so:\[a^{\frac{2}{3}}\times a^{\frac{3}{2}}=a^{\frac{2}{3}+\frac{3}{2}}\]
anonymous
  • anonymous
ya
anonymous
  • anonymous
so to add 2/3 and 3/2 do i make it 8/12 and 18/12
asnaseer
  • asnaseer
oh - I see what you did now. you could have made the common denominator a much smaller number - e.g. \(6=3\times2\)
anonymous
  • anonymous
ahhh
anonymous
  • anonymous
i will try that
asnaseer
  • asnaseer
in any case, your answer is then correct:\[\frac{2}{3}+\frac{3}{2}=\frac{26}{12}=\frac{13}{6}\]
asnaseer
  • asnaseer
your 20 is also correct since 20 = 5 x 4
anonymous
  • anonymous
so 20a to the 13/6
asnaseer
  • asnaseer
so your final answer should have been:\[20a^{\frac{13}{6}}\]
anonymous
  • anonymous
is that the same as 21 to the 1/6
anonymous
  • anonymous
no right?
asnaseer
  • asnaseer
\[a^{\frac{13}{6}}=a^{2\frac{1}{6}}=a^2\times a^{\frac{1}{6}}\]
asnaseer
  • asnaseer
you can leave the answer in the form:\[20a^{\frac{13}{6}}\]
anonymous
  • anonymous
ok thx
asnaseer
  • asnaseer
yw :)
