Term

Identify each part of a logarithm:

logbA = E

 

What part is the base?

What part is the exponent? 

Definition

b is the base

E is the exponent

Term

Re-write this log in exponent form.

log28 = x

Definition
2x = 8
Term
Re-write ln1 = x so it looks like a regular log function
Definition
loge1 = x
Term

What base is implied?:

log1000 = 3

Definition

base 10

whenever there isn't a base, and it just says log, then it is base 10.

Term
How can you re-write logb(a*c)?
Definition
logba + logbc
Term
If given log2(x*200), how would you rewrite it?
Definition
log2x + log2200
Term
How do you re-write logb(a/c)?
Definition
logba - logbc
Term
If given log2(x/200), how would you re-write it?
Definition
log2x - log2100
Term
if given log2(100/x) how would you re-write it?
Definition
log2100 - log2x
Term
if given logbar how would you re-write it?
Definition
rlogba
Term
If given log285 how would you re-write it?
