Match List-I with List-II

Choose the correct answer from the options given below :

A. $$\sqrt{\dfrac{0.81\times\ 0.484}{0.064\times6.25}}=\sqrt{\dfrac{0.81\times\ 4.84}{0.64\times6.25}}=\sqrt{\dfrac{\left(0.9\right)^2\times\ \left(2.2\right)^2}{\left(0.8\right)^2\times\left(2.5\right)^2}}=\dfrac{0.9\times2.2}{0.8\times2.5}=0.99$$

B. $$\sqrt{\dfrac{0.204\times\ 42}{0.07\times3.4}}=\sqrt{\dfrac{20.4\times42}{3.4\times7}}=\sqrt{6\times6}=6$$

C. $$\sqrt{\dfrac{0.081\times0.324\times\ 4.624}{1.5625\times0.0289\times\ 72.9\times64}}=\sqrt{\dfrac{\left(0.9\right)^2\times\left(0.18\right)^2\times\left(6.8\right)^2}{\left(1.25\right)^2\times\left(0.17\right)^2\times\left(27\right)^2\times8^2}}=\dfrac{0.9\times0.18\times6.8}{1.25\times0.17\times27\times8}=0.024$$

D. $$\sqrt{\dfrac{9.5\times0.085}{0.0017\times0.19}}=\sqrt{50\times50}=50$$
