(-6xy⁴)(5xy²) simplified

To simplify the expression (-6xy⁴)(5xy²), you can combine the coefficients (numbers) and add the exponents for the variables with the same base (x and y).

The coefficients are -6 and 5, so their product is -6 * 5 = -30.

The variable x has an exponent of 1 in the first term and an exponent of 1 in the second term, so the product will have an exponent of 1 + 1 = 2.

The variable y has an exponent of 4 in the first term and an exponent of 2 in the second term, so the product will have an exponent of 4 + 2 = 6.

Therefore, the simplified expression is -30x²y⁶.
