`((2.75xx2.75xx2.75-2.25xx2.25xx2.25)/(2.75xx2.75+2.75xx2.25+2.25xx2.25))` के बराबर है।

Options

A. `-5`
B. `0.5`
C. `-0.5`
D. `5`

Answer

B

Explanation

`a=2.75, b= 2.25`
`implies(a^(3)-b^(3))/(a^(2)+ab+b^(2))`
`implies((a-b)(a^(2)+ab+b))/(a^(2)+ab+b^(2))`
`implies (a-b)implies2.75-2.25`
`=0.50`
