Answer:

16x⁶ + 56x³y³z⁴ + 49y⁶z⁸

Explanation:

(4x³ + 7y³z⁴)²

We want to simplify the expression. First, let's rewrite the square:

(4x³ + 7y³z⁴) (4x³ + 7y³z⁴)

Now distribute using FOIL (first, outer, inner, last):

(4x³)(4x³) + (4x³)(7y³z⁴) + (7y³z⁴)(4x³) + (7y³z⁴)(7y³z⁴)

Multiply:

16x⁶ + 28x³y³z⁴ + 28x³y³z⁴ + 49y⁶z⁸

Combine like terms:

16x⁶ + 56x³y³z⁴ + 49y⁶z⁸
