Question

If the square root of C is equal to 8 , what is C equal to ?

Answer 1

The first thing we have to do is turn the statement into an equation:

$\sqrt[2]{C}=8$

To solve for C we can raise the expression on both sides to the square and thus eliminate the root

$\begin{gathered} (\sqrt[2]{C})^2=(8)^2 \\ C=64 \end{gathered}$

Solving we can see that C is equal to 64
