To find the real solution to the radical equation [tex]\(\sqrt{y} = 15\)[/tex]:
1. Start with the given equation:
[tex]\[
\sqrt{y} = 15
\][/tex]
2. To eliminate the square root, square both sides of the equation.
3. Squaring the left side:
[tex]\[
(\sqrt{y})^2 = y
\][/tex]
4. Squaring the right side:
[tex]\[
15^2 = 225
\][/tex]
5. Therefore, equating both sides after squaring, we get:
[tex]\[
y = 225
\][/tex]
Hence, the real solution to the equation [tex]\(\sqrt{y} = 15\)[/tex] is:
[tex]\[
y = 225
\][/tex]
