5^2x+1/25 = 125
5^2x+1/5^2 =125
5^ 2x+1-2 =125 (∴ a^m/a^n = a^m-a^n)
5^ 2x-1 = 125
5^2x-1 = 5^3 ( ∴ if bases are equal powers are also equal )
2x-1 = 3 ( -1 becomes +1 and 3+1=4)
2x = 4
x = 2
5^2x+1/5^2 =125
5^ 2x+1-2 =125 (∴ a^m/a^n = a^m-a^n)
5^ 2x-1 = 125
5^2x-1 = 5^3 ( ∴ if bases are equal powers are also equal )
2x-1 = 3 ( -1 becomes +1 and 3+1=4)
2x = 4
x = 2
