Please type your questions on separate lines. We would prefer one question per post.

<<What is the base of the function

G(x) = log subscript b x

if it's graph has points (16,4)?>>

Ask yourself this:

What number to the 16th power is 4? The answer is 1.09051. That is the base b of the G(x) log function in this case.

<<Using the properties of logarithms how do I rewrite log subscript 5 2/3 + log subscript 5 9/10?>>

log(sub5) 2/3 + log(sub5) 9/10?>>

= log(sub5) [(2/3)*(9/10)]

= log(sub5) 3/5

<<What is the value of

log(sub2) (8 1/2 )?

2^x = 8.5

x log 2 = log 8.5 (use any base)

x = 3.087

I can't remember how to create a system of equations using one cooridnate plain point can anyone help me???
