The coefficient of the product of (-5xy^2) and (-4x^2y) is
the exponent of x in the product is , and the exponent of y is

The coefficient of the product of (-5xy²) and (-4x²y) is 20.

The exponent of x in the product is 3, and the exponent of y is 3.

From the question,

We are to determine the product of (-5xy²) and (-4x²y)

The product of (-5xy²) and (-4x²y) can be determined as shown below

-5xy² × -4x²y

This becomes

Then, we get

The product of the given expressions is

Hence, The coefficient of the product is 20. The exponent of x in the product is 3 and the exponent of y is 3
