Answer:

x = 3

Explanation:

Maybe you want the value of x such that ...

4(6^x) = 864

Solution

Dividing by 4 gives ...

6^x = 216

You may know that 216 = 6^3. Using that, we can equate exponents:

6^x = 6^3

x = 3

Alternatively, we can use logarithms to find x. Taking logs gives ...

x·log(6) = log(216)

x = log(216)/log(6) = 3
