To solve the equation 5^(x+1) - 2*5^(x-1) = 23, we can simplify the terms using the properties of exponents:
5^(x+1) = 5 5^x25^(x-1) = 2 (1/5) 5^x = (2/5) * 5^x
Now, we can rewrite the equation as:
5 5^x - (2/5) 5^x = 23
Combining like terms, we get:
(5 - 2/5) 5^x = 23(23/5) 5^x = 23
Dividing both sides by (23/5), we get:
5^x = 5x = 1
Therefore, the solution to the equation 5^(x+1) - 2*5^(x-1) = 23 is x = 1.
