Provide an appropriate response. The degree of a term that has only one variable (with a nonnegative exponent) is the exponent of that variable. The degree of a term that has more than one variable is the sum of the exponents of the variable factors. That is, the degree of 2x3y4 is 7 since the sum of the exponents (3 + 4) is 7. Given this knowledge, find the degree of the polynomial: y10 + 2xy8 - 5x4y7
