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

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.
