For example:

How many 2s multiply together to make 8?

Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2s to get 8

So the logarithm is 3

We write it like this:

log₂(8) = 3

Notice we are dealing with three numbers:

• the base: the number we are multiplying (a "2" in the example above)

• how often to use it in a multiplication (3 times, which is the logarithm)

• The number we want to get (an "8")
