25^x-1 = 5^(2x-1) - 100

⇒ 5^2x-2 = 5^(2x-1) - 100

⇒ 5^2x-2 - 5^2x-1 = -100

⇒ 5^2x [ 5^-2 - 5^-1] = - 100

⇒ 5^2x [__1 __- __ 1 __] = - 100

25 5

⇒ 5^2x [__1 - 5__] = - 100

25

⇒ 5^2x [__-4 __] = - 100

25

⇒ 5^2x [-4] = -100 * 25

⇒ 5^2x =__ 100 * 25 __ [ - * - = +]

4

⇒ 5^2x = 625

⇒ 5^2x = 5^4

so, ⇒ 2x = 4

⇒__x = 2__

⇒ 5^2x-2 = 5^(2x-1) - 100

⇒ 5^2x-2 - 5^2x-1 = -100

⇒ 5^2x [ 5^-2 - 5^-1] = - 100

⇒ 5^2x [

⇒ 5^2x [
