Question

Please help me!! This is really hard for me and I need a tutor to explain it to me

Answer 1

We want to find the solution of the equation

`x^2=64`

This becomes

`\begin{gathered} x^2=64 \\ we\text{ move the square to the other side it becomes square root, we have} \\ x=√(64)\text{ the square root sign attracts }\pm,\text{ so we have } \\ x=\pm√(64) \\ x=\pm8 \end{gathered}`

Hence the answer is

`\pm8`

Note that square root of 64 is 8
