Question

What’s the answer???(ONLY ANSWER IF YOU KNOW PLEASE)

Answer 1

Answer: B

Explanation:

(a + b)³ = (a + b)(a² - ab + b²)

`(√(2x)` +
`(1)/(x))^(3)` =
`(√(2x)` +
`(1)/(x))`
`(√(2x)^(2) - √(2x)((1)/(x)) +((1)/(x))^(2))`

=
`(√(2x)` +
`(1)/(x))(2x - (√(2x))/(x) +(1)/(x^(2)))`

=
`(√(2x)`
`(2x - ((√(2x))/(x)) +(1)/(x^(2)))` +
`(1)/(x)(2x -(√(2x))/(x) +(1)/(x^(2)))`

=
`2x√(2x) - 2 +(√(2x) )/(x^(2)) + 2 - \frac{√(2x)} {x^(2)} + (1)/(x^(3) )`

=
`2x√(2x)+(1)/(x^(3) )`
