Hi

Apply Distributive Principle (to remove parenthesis) and Combine Like Terms.

-2x^4(x^3+8x^1)+6x^7= -2x^7 - 16x^5 + 6x^7 = 4x^7 - 16x^5 

...........

a%5E0+=+1



%28+x%5Em+%29%28+x%5En+%29+=+x%5E%28+m+%2B+n+%29****

x%5Em%2Fx%5En=x%5E%28m-n%29

%28a%5Ep%29%5Eq+=+a%5E%28p%2Aq%29



%28xy%29%5En+=+x%5En%2Ay%5En
