Please how can this exponential equation be solved 2^3 + 3^2+ 4^5+5^3?

the only option here is to raise everything to the specified power. the only one you can combine is 4^5 which is 2^10

2^3 = 8

3^2 = 9

4^5 = 1024

5^3 = 125

total: 1,166.

sometimes it is easier if you can find a common factor.

for example, have we had 2^3 + 3^2 + 4^5 + 9^3, we could have rewritten everything as:

2^3 + 3^2 + 2^10 + 3^6

then we would bring a common factor in the front:

2^3 * (1 + 2^7) + 3^2(1+3^4)

most of the times, the answer to the question would be in this format too, so that you would not have to calculate everything.
