$2\cdot 5^{-4}\cdot 5^x+15=265$
Learn how to solve problems step by step online. Solve the exponential equation 25^(x-4)+15=265. Apply the property of the product of two powers of the same base in reverse: a^{m+n}=a^m\cdot a^n. Calculate the power 5^{-4}. Multiply 2 times \frac{1}{625}. We need to isolate the dependent variable , we can do that by simultaneously subtracting 15 from both sides of the equation.
