Best ResponseYou've already chosen the best response.0\[2\sqrt{44x ^{3}}\sqrt{7}\sqrt{99x ^{3}}+\sqrt{63}\]

Best ResponseYou've already chosen the best response.0Combine like terms, right? I don't see how to combine \[2\sqrt{44x ^{3}}\] and \[\sqrt{99x ^{3}}\]

Best ResponseYou've already chosen the best response.0before combining see if you can simplify each term first

Best ResponseYou've already chosen the best response.0Oh! like 11 goes into both 44 and 99??

Best ResponseYou've already chosen the best response.0see if u can get rid of the roots!

Best ResponseYou've already chosen the best response.0How would I go about doing that? Right now I have \[2\sqrt{4x ^{3}}\sqrt{7}\sqrt{9x ^{3}}+\sqrt{63}\]

Best ResponseYou've already chosen the best response.0Does it look right? Going in the right direction maybe?

Best ResponseYou've already chosen the best response.0Oh, and I eliminated 7. and the sqrt of 63 is now the sqrt of 9

Best ResponseYou've already chosen the best response.1\(\sqrt {63} = \sqrt {9} \sqrt {7}=...?\)

P.nut1996

Best ResponseYou've already chosen the best response.0Now it looks like \[2\sqrt{4x ^{3}}\sqrt{9x ^{3}}+\sqrt{9}\]

hartnn

Best ResponseYou've already chosen the best response.1\(\sqrt {44x^3} = \sqrt {4} \sqrt{x^2} \sqrt{11x}=...?\) you just can't eliminate 7...

Best ResponseYou've already chosen the best response.1\(\sqrt {44x^3} = \sqrt {4} \sqrt{x^2} \sqrt{11x}=...? \\\sqrt {99x^3} = \sqrt {9} \sqrt{x^2} \sqrt{11x}=...?\)

Best ResponseYou've already chosen the best response.0But & goes into 7 one time and it goes into 63 9 times. Simplifying... Right?

hartnn

Best ResponseYou've already chosen the best response.1so, \(\sqrt {63}\sqrt 7 = \sqrt{9}\sqrt{7}\sqrt{7} = \sqrt{7}[31]=..?\)

hartnn

Best ResponseYou've already chosen the best response.1you see what i did there ^ ?

Best ResponseYou've already chosen the best response.0@hartnn i see what he did

hartnn

Best ResponseYou've already chosen the best response.1\(\sqrt {xy}=\sqrt{x}\sqrt{y}\) ok ? so, \(\sqrt{63}=\sqrt{9}\sqrt{7}=3 \sqrt{7}\) right ?

Best ResponseYou've already chosen the best response.0That does not look like any of my answer choices :(

Best ResponseYou've already chosen the best response.1that was just simplification of constant terms.... \(3\sqrt 7 \sqrt 7= 2 \sqrt 7\) simplification of 'x' terms is still remaining. and more important thing is that you understand....so that you can do other problems on your own...

hartnn

Best ResponseYou've already chosen the best response.1so, do you want me to start over ? or take it from a particular step ?

P.nut1996

Best ResponseYou've already chosen the best response.0Start from the beginning please?

hartnn

Best ResponseYou've already chosen the best response.1right, lets see term by term, so 63 is 9 times 7 so, \(\sqrt {63}= \sqrt {9}\sqrt{7}=...?\)

P.nut1996

Best ResponseYou've already chosen the best response.0Yes. And what do we do with the \[\sqrt{7}\] just leave it where it is?

hartnn

Best ResponseYou've already chosen the best response.1i was getting there... you first tell me what will be \(\sqrt 9 \sqrt7 =... ?\)

P.nut1996

Best ResponseYou've already chosen the best response.0simplify by dividing both \[\sqrt{7}\] and \[\sqrt{63}\] by 7?

hartnn

Best ResponseYou've already chosen the best response.1lets finish 1 term entirely \(\sqrt {63}=\sqrt 9 \sqrt7 =... ?\)

hartnn

Best ResponseYou've already chosen the best response.1so, \(\sqrt {63}=\sqrt 9 \sqrt7 =... ?\)

Best ResponseYou've already chosen the best response.0\[\sqrt{3}\] \[\sqrt{2.6}??\]

hartnn

Best ResponseYou've already chosen the best response.1since \(\sqrt 9=3\) \(\sqrt {63}=\sqrt 9 \sqrt7 =3 \sqrt 7\) got this ?

Best ResponseYou've already chosen the best response.1ok, so now you have constant terms as \(3\sqrt 7\sqrt 7\) can you combine this ? by factoring out \(\sqrt 7 \)

hartnn

Best ResponseYou've already chosen the best response.1\(3\sqrt 7\sqrt 7 = \sqrt 7 [31]=...?\) ok with this ?

P.nut1996

Best ResponseYou've already chosen the best response.0Wait...at the end multiplying \[\sqrt{7}\] by 2?

Best ResponseYou've already chosen the best response.0So now we have part of it completed?

hartnn

Best ResponseYou've already chosen the best response.1yes, now take the terms with 'x'.

Best ResponseYou've already chosen the best response.1so, did you get this ? \(\sqrt {44x^3} = \sqrt {4} \sqrt{x^2} \sqrt{11x}\)

P.nut1996

Best ResponseYou've already chosen the best response.0in front of the \[\sqrt{44x^3}\]

hartnn

Best ResponseYou've already chosen the best response.1there is 2 .. \(2\sqrt {44x^3} = 2\sqrt {4} \sqrt{x^2} \sqrt{11x}=2 \times 2x \sqrt {11x}= 4x \sqrt{11x}\)

P.nut1996

Best ResponseYou've already chosen the best response.0Okay :) \[4x \sqrt{11x}\]

hartnn

Best ResponseYou've already chosen the best response.1similarly, what will be \(\sqrt {99x^3} = \sqrt {9} \sqrt{x^2} \sqrt{11x}=...?\)

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.1\(\sqrt {99x^3} = \sqrt {9} \sqrt{x^2} \sqrt{11x}=3x\sqrt {11x}\) because \(\sqrt 9=3, \: and \: \sqrt {x^2}=x\)

P.nut1996

Best ResponseYou've already chosen the best response.0Oh, I wasn't sure how to break it down. I see what you did now :)

Best ResponseYou've already chosen the best response.0\[x \sqrt{11x}+2\sqrt{7}\] :D

Best ResponseYou've already chosen the best response.1yes. thats correct . i hope you got each step.
