All are incorrect

Explanation:

Required

Determine which is correct or not

`(a)\ 2x * 2x = 4x`

This is incorrect because:

`2x * 2x = 2 * 2 * x*x`

`2x * 2x = 4x^2` ---- fixed

`(b)\ 3x^3 * 3x^3 = 9x^9`

This is incorrect because:

`3x^3 * 3x^3 = 3 * 3 * x^3 * x^3`

`3x^3 * 3x^3 = 9x^(3+3)`

`3x^3 * 3x^3 = 9x^6` ---- fixed

`(c)\ 4x(4x + 5) =8x + 5`

This is incorrect because:

`4x(4x + 5) =4x * 4x + 4x * 5`

`4x(4x + 5) =16x^2 + 20x` ---- fixed
