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)^nF)^G=?

I've uploaded a jpeg attachment of what I propose but need help please...

Thanks!
