The degree of the polynomial 10 x squared plus 2 x to the m th power y minus 4 y is 3 What is the value of m ?

The term 2x^m y has total degree m + 1, since the exponents of x and y are added. The other terms, 10x² and −4y, have degrees 2 and 1. For the polynomial’s degree to be 3, m + 1 must equal 3, so m = 2. The correct choice is 2.
