2)

3)

Explanation:
To write logs of the form
in their exponential form, you take the base b and put it to the power of x and then set that equal to a:
.
1. Here, b = 5, a = 25, and x = 2, so:

2. In this problem, b = 5, x = 2, and a = x, so:

3. Finally, here, b = b, a = 64, and x = 3, so:

Hope this helps!
