Answer:
1 tenth=10 right?
1 tenth+2 tenths= 3 tenths or thirty
plus 3 more tenths is 6 tenths or 60
Step-by-step explanation:
Try 60
6y+9=18
6y=2
y=1/3
p^(-9) or 1/p^9
Here we have:
(5p)^(-7)
----------------
(20p)^2
Let's temporarily remove the coefficient 5/20 and reduce it to 1/4.
then we have:
1 1 1
(1/4) ------------- = (1/4) -------------- = ------------
p^7*p^2 p^(7 + 2) p^9
