The square root and 2th power exclude each other as they are both doing the opposite. You therefore get: \[4x^2  3 = 64\]

4x^2 = 67 x^2 = 67/4 x = 67/4 , 67/4

shaun has it right untill he gets rid of power it should be: \[\LARGE x^2=\frac{67}{4}\] then... \[\LARGE x=\pm \sqrt{\frac{67}{4}}\] but first of all... just want to ask you. is this the given: \[\LARGE \sqrt{(4x^23)^2}=64 \]

Actually I don't know whether the square root is for everything or only for (4x^23)^2

the whole sqrt is squared? \[(\sqrt{4x^23})^2=64\]

Okay, sorry. I'm a bit confused. I just realised the question does not even have a square root, lol. Sorry!

\[ (4x^23)^2=64 \\ (4x^23)=8 \\ 4 x^2 = 11\\ x^2 = \frac {11}4\\ x=\pm \sqrt{\frac {11}4}\\ x =\pm \frac {\sqrt {11}} 2 \]
