Verified answer

[√(16x^2) * √(144y^2)] / 2xy = [4x * 12y] / 2xy = 24

QED

sqrt 16x^2 = 4x, sqrt 144y^2 =12y so 4x*12y/2xy

48xy/2xy= 24

Doing this term by term we get

√16 * √x^2 * √144 * √y^2 ÷ 2 ÷ x ÷ y

= 4 * x * 12 * y ÷ 2 ÷ x ÷ y

= 24

Thus, the answer is (c).

Answer is c.

Use rt16 = 4 and rt(x^2) = x etc. This is a very simple problem.

(√16x²*√144y²)/2xy=

(4x*12y)/2xy=

48xy/2xy=

24

answer is c. 24
