Finding the largest coefficient in its corresponding term

[cheahchungyin]

f(x)=(1.2x^-11 + 1.5x⁷)²⁰ (1.25x²¹ + 1.7x^-0.05)⁵⁰

Given the function above, by binomial expansion, Xⁿ appears to be the term with the largest coefficient. Determine n and hence state the corresponding coefficient.

Would like to know the method of doing this question in an easier way.
