SIMPLIFY:
ROOT 0F 7 * ROOT OF 14

SIMPLIFY:
ROOT OF 1/5

EVALUATE, IF POSSIBLE:
ROOT OF 9/16
(I GOT 3/4 BUT I WAS NOT SURE IF THAT WAS CORRECT OR NOT)

SIMPLIFY. ASSUME X REPRESENTS A POSITIVE NUMBER:
ROOT OF 45X^4




ROOT 0F 7 * ROOT OF 14 = sqrt 7 * sqrt 7 * sqrt 2 = 7 sqrt 2

ROOT OF 1/5 = 1 /(sqrt 5)

ROOT OF 9/16 = sqrt 9/sqrt 16 = 3/4

sqrt(45X^4) = sqrt 45 * X^2
