=SUMPRODUCT(5^(ROW(1:4))/FACT(ROW(1:4)))

Hi. This returns 64.375

Ont sure if that's what the op wants, but just to mention one of a few
other ways for the above ...

=SERIESSUM(5,1,1,1/FACT(ROW(1:4)))
'or
=SERIESSUM(5,1,1,1/{1,2,6,24})

also returns 64.375

Assume you want to add up

5/1! +( 5^2)/2! + (5^3)/3! + (5^4)/4!

use

=SUMPRODUCT(5^(ROW(1:4))/FACT(ROW(1:4)))

follow evaluate formula and watch how the calculation works - that will help
