Hi--I'm new to the forum (and suck at maths) and need to construct an equation for the following:

[(Sum of(A + B))/C] x [D/E] x[(Sum of (F)) to the power of the mean of G]=? Can someone please present me with the correct notation? I've tried it as follows but have no idea if it is accurate.

((∑_(k=0)^n▒〖(A+B)〗)/T)(D/E) (∑_(k=0)^n▒F)^G=?

Thanks!
