Answer:
3^x-8=8 then x=log_3(16)
3^(x-8)=8 then log_3(8)+8
Step-by-step explanation:
So if it is 3^x-8=8
then 3^x=16
and then convert to logarithmic form you write it as log_3(16)=x
_3 means the subscript (the base) is 3
So if it is 3^(x-8)=8
then the log form is log_3(8)=x-8
add 8 on both sides log_3(8)+8=x
A culture started with 1,000 bacteria. After 3 hours, it grew to 1,100 bacteria. Predict how many bacteria will be present after 17 hours.

Answer:
m = 
Step-by-step explanation:
Given
+ 
= 
Multiply through by 15 to clear the fractions
15 is the lowest common multiple of 3, 5 and 15
10 + 9m = 31 ( subtract 10 from both sides )
9m = 21 ( divide both sides by 9 )
m = 
=
