Question

25 raised to power 2x-1=5 raised to power 2x-1-100

Answer 1

Answer: 1/2

Step-by-step explanation:

4x-2 = 2x-1

2x = 1

x =1/2

Answer 2

Answer:

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] 25 = 100 52x [ 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
