Choose the correct simplification of (5x2y3z4) (6x3y4z2).

30x5y7z6

30x6y12z8

11x5y7z6

11x6y12z8

Multiply the numerical coefficients of both terms and add the exponents of the variables: x, y, and z to answer the problem above. The simplification is shown below.

(5x²y³z^4) x (6x³) (y^4) z² = 30 (x^5) (y^7) (z^6)

Thus, the answer is the first choice.
