So, We Have:
[tex] 4y^{2} = 256
[/tex]
We Need To Solve.
Lets Start By Finding the Square Root Of 256.
[tex]4y = \sqrt{256} \\
We\ Know\ That\ \sqrt{256} = 16. So,\ The\ Equation\ Becomes:\\
4y = 16\\
Divide\ Both\ Sides\ By\ 4.\\
y = 16/4\\
16/4 = 4,\ So:\\
Y = 4\\
Check:\\
4*4 ^{2} = 256\\
4*4 = 16.\\
16^{2} = 256\\
256 = 256\\
This\ Is\ True.\ So,\ y = 4.[/tex]
