2^3 + 2^4
= 8 + 16
= 24
Don't know how much simpler we can make it.
How were you going to "expand" it?
is there any trick I can use to solve the question below without expanding:
2^3 + 2^4

Like there are rules for multipling eponents with the same base, I was wondering if there were rules for addition. If I were to get some complicated like:
3^-2/3 + 3^5/8
... it would take a longer time to solve.
3^-2/3 + 3^5/8
... it would take a longer time to solve.
no
If the bases are different, you cannot add or subtract them
e.g. x^3 + y^2 stays that way
If the bases are the same in addition, you can usually factor.
e.g. x^5 + x^2 = x^2(x^3 + 1)

Thank you :)
