Newbie Joined: Jul 2015 From: United States Posts: 14 Thanks: 0  Another Pythagorean Theorem question Use the Pythagorean Theorem to fine what b equals. I'm confused about the square root, I know the square root of something squared is just the number, but what about when there's a number and then the square root. Please help. Thanks in advance.

$(a\sqrt{b})^2 = a^2\cdot\sqrt{b}^2 = a^2b$
