5y + 5y³ can not be added. You can only add "things" that are the same.
Examples
3a + 5b + 4a = 7a + 5b
2 x ² + 6 y + 7 x ² = 9 x ² + 6 y
5 x ² + 2 x ³ + 4 x ³ + 8 x ² = 13 x ² + 6 x ³

I think it's
4
5y+5y cubed =10y

To clarify entropy_rhythm's answer, it depends on what you mean.
5y+5*(y^3) can't be further added
5y+(5y)^3=5y+(5^3)*(y^3)= 5y+125*(y^3), and those terms can't be further added
(5y+5y)^3=(10y)^3= (10^3)*(y^3)=1000*(y^3)

You can't add them but you can factor to 5y(1+y^2)

hmm..
5y + 5y^3 is a binomial expression having the same variables but different exponents, which make them unaddable..
all you can do here is to factor out the same expression for it to look like:
5y(y^2 + 1)..
but addition is impossible, unless the variables have values which are numbers..
hope this helps!

(5y + 5y)^3 = (10y)^3 = 1000y^3

no, you can't add numbers with a different variable. y and y cubed are different variables.

no they are not the same value. the exponents have to match in order to add them. (or subtract)
