Answer:

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
