the distributive law of multiplication says:

(a + b) * (a + b) equals:

a * (a + b) plus b * (a + b) which equals:

(a*a) + (a*b) + (b*a) + (b*b).

since a*b) is the same as (b*a), this can be shown as:

(a*a) + (a*b) + (a*b) + b*b) which can be shown as:

a^2 + 2*a*b + b^2

if you let a = x^n and b = y^m, this becomes:

%28x%5En%29%5E2+%2B+2%2Ax%5En%2Ay%5Em+%2B+%28y%5Em%29%5E2 which can be shown as:

x%5E%282n%29+%2B+2%2Ax%5En%2Ay%5Em+%2B+y%5E%282m%29

Which is "simplified?

%28x%5En%2By%5Em%29%5E2 ?
Or x%5E%282n%29+%2B+2x%5En%2Ay%5Em+%2B+y%5E%282m%29 ?
