Best ResponseYou've already chosen the best response.0\[(\sqrt[3]{x9})^3\] If you cube a cubed root you just remove them both. \[\sqrt[3]{a^3} = \sqrt[3]{a}^3 = a^{\frac{3}{3}} = a^1 = a \]

Best ResponseYou've already chosen the best response.0its whats inside the radical thats confusing me

Best ResponseYou've already chosen the best response.0well. i have another problem thats like that and i just dont know what to do with (xanything)^anything

Best ResponseYou've already chosen the best response.0Just expand it and simplify as much as possible. Unless you have an equal there you can't really solve for x.

Best ResponseYou've already chosen the best response.0so you foil within the radical to expand it?

anonymous

Best ResponseYou've already chosen the best response.0Well if it's something cubed inside a cubed root, there's no need to foil it cause the two cancel eachother out. Otherwise yeah you'd have to distribute (foil) and hope it turns out nicely.

Best ResponseYou've already chosen the best response.0so the answer is just x9

Best ResponseYou've already chosen the best response.0thank you, can you help me with sqrt 25(x+2)^4

Best ResponseYou've already chosen the best response.0Can you quickly rewrite each of those factors as a square?

Best ResponseYou've already chosen the best response.0And \((x+2)^4 \) is what squared?

Best ResponseYou've already chosen the best response.0Oh. well what if I asked you what \((2^2)^2\) was. Do you know that?

anonymous

Best ResponseYou've already chosen the best response.0Yes, but don't think about it that way ;p

Best ResponseYou've already chosen the best response.0Think about it as \(2^4\)

Best ResponseYou've already chosen the best response.0the teacher i have sucks. so probably have but not the way your explaining it

Best ResponseYou've already chosen the best response.0Hrm. Ok, well so if raising something to a power multiplies exponents, then taking the root of a power divides the exponent.

Best ResponseYou've already chosen the best response.0For example. \[\sqrt{5^4} = 5^2\] \[\sqrt[3]{7^{12}} = 7^4\] etc.

Best ResponseYou've already chosen the best response.0So if you have \[\sqrt{a^4} =\ ?\]

anonymous

Best ResponseYou've already chosen the best response.0okaie. so would (x+2)^4 would just be x+2 ^ 2. and the answer to your question is a^2

anonymous

Best ResponseYou've already chosen the best response.0Yes precisely. So for your problem you had \[\sqrt{5^2(x+2)^4} =\ ?\]

anonymous

Best ResponseYou've already chosen the best response.0well it was 25 which = 5^2.

anonymous

Best ResponseYou've already chosen the best response.0Right. Same difference, so take the square root of that and you get?
