The coefficient of the product of (-5xy2) and (-4x2y) is . the exponent of x in the product is , and the exponent of y is

The coefficient is the number, therefore -5 and -4,
The exponent of the first x is 1 and the second x is 2, if the 2 is meant as an exponent. The first exponent of y is 1 and 5e second y is 2
