Find the principal square root of numbers and simplify square root problems.
Nick has realized he can use the Pythagorean Theorem to estimate square roots. He does this by drawing a specific right triangle and measuring its hypotenuse with a ruler. The Pythagorean Theorem states that a right triangle's hypotenuse is the square root of the sum of the squares of the legs of the triangle. Nick wants to estimate
