Question

Please help! Radical Functions, how would I solve this equation?

Answer 1

isolate the cuberoot, then cube both side of the equation, then the cube root will goes away, then u can solve for x easily

Answer 2

How would I isolate the cube root?

Answer 3

never mind, it was fifth root, so subtract 3 on both side, u will have 3 times fifth root (x+2)^3, so you will have 3 times fifth root (x+3)^3=24

Answer 4

then raise both side of the equation to the fifth power to cancel out the fifth root

Answer 5

Sorry had to step away for a bit. I understand it so far and I got up to 3 5^sqrt(x+2)^3=24 but how would I raise 5^sqrt(x+2)^3 to the 5th power?

Answer 6

\[3\sqrt[5]{(x+3)^3}=24\]
\[\sqrt[5]{(x+3)^3}=8\]
\[(x+3)^{3}=8^5\]
\[\sqrt[3]{(x+3)^3}=\sqrt[3]{8^5}\]
\[x+3=\sqrt[3]{8^5}\]
now u can finish the rest

Answer 7

Is it possible for us to subtract 3 to get x alone? (srry I really suk at this type of math)

Answer 8

yea, it is possible, that's how you would solve for x.

Answer 9

Thanks so much then!
