|
|
logb X = y |
>b^y = x |
|
|
|
logb XY |
logb X + logb Y |
If you're multiplying XY then it's rewritten as x+y If you're dividing X/Y then it's rewritten as x-y |
|
|
logb X/Y |
logb X - logb Y |
If you're multiplying XY then it's rewritten as x+yIf you're dividing X/Y then it's rewritten as x-y |
