What will come in place of the question mark (?) in the given questions ?
Solution
Expression : $$\frac{125^{2}\times\sqrt{(15)}\times5^{3}}{\sqrt{(375)}}=5^{11-?}$$
=> $$\frac{(5)^6 \times \sqrt{15} \times (5)^3}{5 \sqrt{15}} = 5^{11-?}$$
=> $$5^{6 + 3 - 1} = 5^{11-?}$$
=> $$11 - x = 8$$
=> $$x = 11 - 8 = 3$$
