Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 512\frac{5}{12}

Concept

Basic Calculation

Application

(√1875 / √3888 ÷ √1200 / √768) × √175 / √1792

Rewriting the numbers as -

[(25√3 / 36√3) ÷ (20√3 / 16√3)] × (5√7 /16√7)

x = (25/36) × (16/20) × (5/16)

x = (25/(36 × 4))

Taking under root from each side

√x = √(25/(36 × 4))

√x = (5/12)
