`(137xx137+133xx133+18221)/(137xx137xx137-133xx133xx133)` के बराबर है।

Options

A. `4`
B. `270`
C. `1/4`
D. `1/270`

Answer

C

Explanation

`a=137, b=133`
`implies(axxa+bxxb+ab)/(axxaxxa-bxxbxxb)`
`implies(a^(2)+b^(2)+ab)/(a^(3)-b^(3))`
`implies (a^(2)+b^(2)+ab)/((a-b)(a^(2)+b^(2)+ab))implies1/(a-b)`
`implies 1/(137-133)implies1/4`
