3^8 • 5^2 = a^b , where both a and b are positive integers, find the smallest possible value for a + b.
405^2 gives 407 as an answer we figured out, but I'm not sure how to show how I got there and it seems too simple to be the best answer.
Thats the question. I was wondering how to do the question ie method and what the answer would be. Any help is appreciated.
