Correct

Answer 2

Answer: Option C is correct that is
`16x^(10) +121+88x^5`

Step-by-step explanation:

we have been given with the expression

`(4x^5+11)^2`

we will use the formula of

`(a+b)^2=a^2+b^2+2ab`

Here a is equal to
`4x^5`

And b is equal to 11 substituting the values of a,b in the formula we will get

`(4x^5+11)^2=(4x^5)^2+11^2+2(4x^5)(11)\\\\=16x^(10) +121+88x^5`
