change the exponential expression to an equivalent expression involving a logarithm.

4.1=a^2

log a = 2

forgot to type the 4.1

log a 4.1 = 2

To change the exponential expression 4.1 = a^2 to an equivalent expression involving a logarithm, we need to use the logarithmic property that states:

If a^x = b, then log base a of b = x.

In this case, we have 4.1 = a^2. To rewrite it in terms of a logarithm, we can use the property mentioned above:

log base a of 4.1 = 2

Therefore, the equivalent expression involving a logarithm is log base a of 4.1 = 2.
