Find the power and root, if they are real numbers. 25 36 3/2 Step 1 We can evaluate expressions of the form am/n in two ways: amin = (a1/nym = (a)m or am/n = (am) 1/n = am. For this problem we will use the first form because we will be taking the square root first, and both 25 and 36 are perfect squares. 25 3 (35) /2 = 36 3 Step 2 a Simplify using the fact that v 25 () - 36 = BD = a
