Im just guessing here, not sure if im right, but if you subtract 2 from 18 you get 16, so subtract 2 from 27 and get 25 i guess so probably 16:25 or 16 to 25 or 16/25 (all 3 ways to write it)
Log₅(25/125)
=log₅(1/5)
=log₅(1)-log₅(5)
=0-1
=-1
-------------------------------------------
USE:
log₅(x)-log₅(p)=log₅(x/p)
Remember that:
5⁰=1,
5¹=5
Answer:
C.
Step-by-step explanation:
To get from (16,12) to (12,9) you would multiply both 16 and 12 by 3/4 to get 12 and 9.
3k-2=2k+4
-2k. -2k
k-2=4
+2. +2
k =6
