Solving exponential and logarithmic equations in exercise, solve for x.
e- 0.01x - 5.25 = 0

The solution for x is:

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

Now, the ln is the inverse operation to the exponential, so we apply the ln to both sides of the equality.
