The degree of a polynomial in x is the greatest exponent of x when the polynomial is written as a sum of terms such as $$a_i$$$$x^i$$, where i is a positive integer and $$a_i$$, is a number. For example, the degree of $$9x^3 + 3x^5 – 100x$$ is 5. What is the degree of the polynomial$$(x+4x^3)^2$$$$(x^5-7）$$？
