WebLogarithms Can Have Decimals. On Introduction to Logarithms we saw that a logarithm answers questions like this: How many 2 s do we multiply to get 8? Answer: 2 × 2 × 2 = 8, so we needed to multiply 3 of the 2 s to get 8. So the logarithm is 3. And we write "the number of 2s we multiply to get 8 is 3 " as. WebOne important property of logarithms is that multiplication inside the logarithm is the same thing as addition outside of it. In the same way division is "the same" as subtraction in logarithms. So our expression is the same as. But also, exponents can be moved outside in the same way. is basically , so .
