If square root (x) = 16 , what is the value of square root (4 times x) ?

Answer Choices

Answer

The expression square root (4 times x) is equivalent to (square root 4)(square root x) , and square root 4 = 2 . Since square root x = 16 , it follows that square root (4 times x) = (square root 4)(square root x) = (2)(16) = 32 .
