`root(3)(3.5)+root(3)(2.5))`
`{(root(3)(3.5))^(2)-root(3)(8.75)+(root(3)(2.5))^(2)}` का मान ज्ञात करें।

Options

A. `5.375`
B. `1`
C. `6`
D. `5`

Answer

C

Explanation

`(root(3)(3.5)+root(3)(2.5))`
`{(root(3)(3.5))^(2)-root(3)(8.75)+(root(3)(2.5))^(2)}`
`x=root(3)(3.5)`
`y=root(3)(2.5)`
`implies(x+y)(x^(2)-xy+y^(2))`
`impliesx^(3)+y^(3)`
`implies(root(3)(3.5))^(3)=(root(3)(2.5))^(3)`
`implies3.5+2.5=6`
