rewrite the following exponential equation logarithmic form
81=9²

Answer:

The logarithmic form of the exponential equation 81 = 9² is:

log base 9 of 81 = 2

Step-by-step explanation:

To rewrite the exponential equation 81 = 9² in logarithmic form, we need to determine the base of the exponential equation and the exponent.

In this case, the base is 9 and the exponent is 2.

The logarithmic form of an equation expresses the exponent as the result of a logarithm.

Using the base 9, we can write the equation as:

log base 9 of 81 = 2

This equation states that the logarithm of 81 with base 9 is equal to 2.

Answer:

81 = 4log(3)

Step-by-step explanation:

a^b = b log(a)

81 = 9²

9² = 2 log(9)

2log(9) = 2log(3²)

2log(9) = 2×2log(3)

81 = 4log(3)
