| LOGARITHMS |
|
Definition of Logarithm:
For
positive b and y, b ≠ 1, logb y = x if and only if (iff)
bx
= y.
The statement x = logb y is read as “x is the log on a base b
that gives the value y.”
(Remember that a logarithm is an exponent.)
Note: When a base is not written using log, it is understood to be
10.
log10x =
log x. |
