To simplify (3x³y²z + 5xy³z²)², we can use the formula for the square of a binomial:

(a + b)² = a² + 2ab + b²

In this case, a is 3x³y²z and b is 5xy³z². Substituting these values into the formula, we get:

(3x³y²z + 5xy³z²)² = (3x³y²z)² + 2(3x³y²z)(5xy³z²) + (5xy³z²)²
                   = 9x⁶y⁴z² + 30x⁴y⁵z³ + 25x²y⁶z
