(a/b)^x-1 = (b/a)^x-3

then the value of x?

• (b/a)^(1-x)=(b/a)^(x-3)
  1-x=x-3
  x=2

• (a/b)^x-1 = (b/a)^x-3
  so that (b/a)^x-3 can be written as (a/b)^3-x
  therefore bases are equal,powers are also equal
  x-1=3-x,after solving this one we get x=2.

• (b/a)^[1/x-1] = (b/a)^x-3. thus 1/x-1 = x-3
  solving this we get x = 1,3
