Question 101
What should come in place of the question marks in the following equations?
$$\frac{?}{24}=\frac{72}{\sqrt{?}}$$
Solution
Expression : $$\frac{?}{24}=\frac{72}{\sqrt{?}}$$
=> $$(?)^{(1+\frac{1}{2})}= 72 \times 24$$
=> $$(?)^{\frac{3}{2}} = 1728 = 12^3$$
Multiplying exponents by $$(\frac{2}{3})$$ on both sides
=> $$(?)^{(\frac{3}{2} \times \frac{2}{3})}= (12)^{(3 \times \frac{2}{3})}$$
=> $$(?)=12^2=144$$
=> Ans - (D)
