What is [(2^-x) - 1] divided by [(2^x) - 1] . Solve it.

We need to simplify the expression (2^-x -1) / (2^x
-1)

First , we will rerite 2^-x =
1/2^x

==> (2^-x) -1= (1/2^x) -1 = (1-2^x)/2^x=
-(2^x-1)/2^x

Now we will substitute into the
expression.

==> (2^-x)-1)/ (2^x -1) = (-2^x-1)/2^x]
/ (2^x-1)

Now we will reduce similar
terms.

==> -1/2^x / 1
-1/2^x

==> (2^-x)-1) / (2^x-1) = -1/2^x =
-2^-x

Now we will try and find the
solution.

==> -1/2^x =
0

Then, there is no solution for the equation because the
numerator is a constant numbers and can not be
zero.

Then, there is no
solution.
