`((2.697-0.498)^(2)+(2.697+0.498)^(2))/(2.697xx2.697+0.498xx0.498)` का मान क्‍या है?

Options

A. `4`
B. `2`
C. `2.199`
D. `3.195`

Answer

B

Explanation

According to the question
`implies((2.697-0.498)^(2)+(2.697+0.498))/(2.697xx2.697+0.498xx0.498)`
Let `a=2.697`
`b=0.498`
`implies((a-b)^(2)+(a+b)^(2))/(a^(2)+b^(2))`
`implies (a^(2)+b^(2)-2ab+a^(2)+b^(2)+2ab)/(a^(2)+b^(2)`
`implies(2(a^(2)+b^(2)))/(a^(2)+b^(2))implies2`
