Respuesta :
I suppose you mean 5y^8.
When y = 4, we have,
5(4)^8 = 5 x 65,536 = 327,680
When y = 4, we have,
5(4)^8 = 5 x 65,536 = 327,680
Answer: Well if it is this:
Evaluate the expression when y = 4.
5 + y + 8
Than your answer will be:
17
If it is like this:
Evaluate the expression when y = 4.
5 x y x 8
Than your answer will be:
160
I am only doing these expressions but they should be right.
