`(5.71xx5.71xx5.71-2.79xx2.79xx2.79)/(5.71xx5.71+5.71xx2.79+2.79xx2.79)` का सरलीकरण मान क्या है?

Options

A. 8.5
B. 8.6
C. 2.82
D. 2.92

Answer

D

Explanation

`a=5.71,b=2.79`
`implies(axxaxxa-bxxbxxb)/(axxa+axxb+bxxb)`
`implies(a^(3)-b^(3))/(a^(2)+ab+b^(2))`
`implies((a-b)(a^(2)+b^(2)+ab))/((a^(2)+ab+b^(2)))`
`implies(a-b)`
`implies5.71-2.79`
`implies2.92`
