Question 6837: I would appreciate it if a tutor could please verify my answer for the below problem:

**There is a superscript 3 before the square root symbol**
^3 sqrt(x^2-7x-15) +3=0

My answer:

^3 sqrt(x^2-7x-15) +3=0
(^3 sqrt(x^2-7x-15)^3=-3^3
x^2-7x-15=-27
x^2-7x+12=0
(x-4) or (x-3)
x-4=0 or x-3=0
x=4 or x=3

In advance, thank you for your assistance!
