Calculate sqrt(60x)*sqrt(12x)*sqrt(63x)*sqrt(42x). Express your answer in simplest radical form in terms of x. Note: When entering a square root with more than one character, you must use parentheses or brackets. For example, you should enter sqrt(14) as "sqrt(14)" or "sqrt{14}".
+36916 = sqrt (x^4 * 60 * 12*63*42)
= x^2 sqrt ( 4 * 15 * 4 * 3 * 3 * 3*7* 3 * 14)
= 4 *3 *3 x^2 sqrt ( 3*5* 7* 7*2)
= 7* 36 x^2 sqrt(3 *5 *2)
=252 x^2 sqrt (30)
