Question

`(sqrt(72)xxsqrt(363)xxsqrt(175))/(sqrt(32)xxsqrt(147)xxsqrt(252))` का मान क्‍या है?
A. `55/42`
B. `45/56`
C. `45/25`
D. `55/28`

Answer 1

Correct Answer - D
`(sqrt(72)xxsqrt(363)xxsqrt(175))/(sqrt(32)xxsqrt(147)xxsqrt(252))`
`implies(sqrt(2xx2xx2xx3x3)xxsqrt(11xx11xx3xxsqrt(5xx5xx7)))/(sqrt(2xx2xx2x2xx)xxsqrt(3xx7xx7)xxsqrt(2xx2xx3xx3xx7)`
`implies(6sqrt(2)xx11sqrt(3)xx5sqrt(7))/(4sqrt(2)xx7sqrt(3)xx6sqrt(7))`
`implies (6xx11xx5)/(4xx7xx6)=55/28`
