Answer:

All are incorrect

Step-by-step 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
