If the 7 is in superscript:
(x +5)7
x to the 7th + 5 to the 7th
x to the 7th + 5 x 5 x 5 x 5 x 5 x5 x 5 x 5
x to the 7th + 78 125
If the 7 is a factor:
(x + 5)7
7x + 35

1) in this expression (x+5)7 means (x+5)*7
2) asterisks (*) or the multiplication symbol has the higher precedence always compared to the addition and subtraction
3) so 7 is multiplied wit both the terms x and 5
4) (x+5)7= (7x+35)
5) next if x has a value it is multiplied wit 7
6) then it is added to 35 and u get the answer
(this is surely the right answer)

That is the answer...(x+5)7 or 7(x+5) is
7x +35 in simplest terms.

using the distribution process:
x times 7 = 7x. then,
5 times 7 = 35. add them up:
the answer is 7x+35
