(a) Express the following radicals in their exponential forms,

(b) Then use your calculator and the rules of exponents from Section 1.1 to solve for y.

(1) y=3.17 (a) (b) To find 510.5, enter 51, hit the y = 31/2. 171/2 y= (3-17)/2 = 51 1/2 = 510-5 (Rule 4) key, then enter 0.5 and hit the key to learn 510.5 = 7.14143. Recalling that an even root can be positive or negative, y = 7.14143 Compare with Problem 1.25 (a). (2) y=22.45
