How do I solve this? \[-7\sqrt[2]{3x-8} + 3 = -4x + 7\]

OpenStudy (anonymous):

\[-7\sqrt[2]{3x-8} + 3 = -4x + 7\]

OpenStudy (anonymous):

\[-7\sqrt{3x-8}=-4x+4\\ \sqrt{3x-8}=\frac{-4x+7}{-7}\] then square both sides.

But there is a 2 infront of the square root of 2x-8 How do i get rid of that?

OpenStudy (compassionate):

You want to start first by solving the squareroot.

OpenStudy (anonymous):

Don't you think that 2 simply means square root.

OpenStudy (anonymous):

@imron07 is right. if there were a 3 there it would mean ^(1/3). The 2 just means ^(1/2) which is the same thing as square root

Oh that makes so much sense. Thanks guys, I really appreciate it.
