Question

If 1/5^-(2x-1)=3125 find x

Answer 1

x =-2

Explanation:

1/5^(2x - 1) =3125

5^-2x +1 =5^5

1-2x =5

-2x =5-1

-2x =4

X =4/-2

x =-2

Answer 2

1/5^-(2x-1) = 3125

Write them in positive exponent form

We get

5^(2x-1) = 3125

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

2x - 1 = 5

2x = 5+1

2x = 6

x = 3

Hope this helps.
