Step 1

Hi Tatiana, let's solve this exponential equation together. We need to find the value of x that satisfies six to the power of one minus two x equals five to the x.

Solving an Exponential Equation

$$6^{1-2x} = 5^x$$

Step 2

Since the bases six and five are different and cannot be easily written with a common base, we should take the natural logarithm of both sides to bring the exponents down.

Step 3

Using the power rule for logarithms, we can move the exponents to the front as multipliers.

Step 4

Now, let's distribute the natural log of six on the left side of the equation.

Step 5

Our goal is to isolate x. Let's move all terms containing x to the right side by adding two x times the log of six to both sides.

Step 6

Now, we can factor out the common factor of x from the right side.
