Question

please answer fast its kinda urgent​

Answer 1

The answer is as given below
The reason why I assumed n to be 2 is because the the first part of the equation 5^2n-1 needed to be greater than 100 and the second part 25^1n-1 needed to be smaller than 100. So, 5^2*2-2 would give me 5^3 which is 125 and 5^2*2-2 would give me 5^2 which is 25. So 125-25 is 100. Therefore the solution to the equation is 2.
