To solve the exponential equation, we apply natural logarithm from both sides of it:

Now, we apply the power rule of the logarithms:


Now, we apply the distributive property on the left side of the equation:

Now, we subtract xln(5) from both sides of the equation:

Now, we subtract ln(4) from both sides:

Now, we factor x on the left side:

Thus, the exact solution is:

And the solution rounded to three decimal places is:
