Question

domain of loga(x^2-9)

Answer 1

is the logA supposed to be there?

Answer 2

yes

Answer 3

the A too? I don't know what loga is ...

Answer 4

never mind your right

Answer 5

i figured it out

Answer 6

oh, ok, cool

Answer 7

can you help me with some other log questions

Answer 8

possibly...i can give it a shot, lol

Answer 9

ok one sec

Answer 10

If logb2=x and logb3=y, evaluate the following in terms of x and y:

logb(18)
logb(108)
logb(8/9)
(logb(81))/(logb(8))

Answer 11

i don't completely understand. Logb2, does that mean log base 2?

Answer 12

yes

Answer 13

log base b^2

Answer 14

err...still not getting it completely, sorry. So \[x=\log_{b} 2 \]

Answer 15
