Answer 2

in math??

Answer 3

if so the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication.

hope it helps

Answer 5

thank you

Answer 6

Here are the basic rules to logarithms
\[1.log_{b}(mn)=log_{b}(m)+log_{b}(n)\]
\[2.1.log_{b}(\frac{m}{n})=log_{b}(m)-log_{b}(n)\]
\[3.log_{b}(m^{n})=n*log_{b}(m)\]
I hope this helps you =)

Answer 8

this video has one way to remember how to use logs

Warning: the audio on the video is a bit loud, so you may want to lower the volume on your speakers/headphones

the basic idea of the video is that you use logs to get exponents out of the trees

another way to remember it: if you have some unknown box in the tree, you have to cut down the tree (ie log it) to get the box down so you can see what is in the box. When you see what's in the box, that's like finding out the unknown variable
