Step-by-step explanation:
3 to the power of 5
3^5
= 3x3x3x3x3
= 243
For this one I'm going to assume that 4 7a means 4 * 7a...
(8 + 7a) + 4 * 7a =
8 + 7a + 28a =
8 + 35a
If I read it wrong and 4 7a is actually 47a then...
(8 + 7a) + 47a =
8 + 54a =
2(4 + 27a)
F(x)=x^2-4x+7

Constant is otherwise called term independent. It should not contain any other letters.
So, a constant without a variable best describes a constant.
