exponent addition

What does 2^5 + 2^5 + 3^5 + 3^5 + 3^5 =?

I chose 4^5 + 9^5

but the answer is 2^6 + 3^6

Please explain how you get the answer[/quote]

2(2^5)+3(3^5)

easier to understand now?

2x2^5=2^6
3x3^5=3^6

All you have to do is group them.

Also take a quick look at this question I think u will understand it even further:

Tj ,
it is as simple as ...if u calculate....2^5 =32 and if u add 2^5 = 32
ans is 64...

now 4^5 is not equal to 64..So wrong

and i would like to mention 1 property which exists in the case of "2" only
= 2^2+2^2 =2^3
2^3+2^3 = 2^4
2^4+2^4 = 2^5.....
always rem......

Easier way

take 2^5(1+1) + 3^5(1+1+1)
2^6+3^6
