To simplify this, you would have to turn b^-2 into a positive exponent.
To do this, we have to flip b^-2, which would get rid of the negate from the exponent: -2
3a^4 b^-2 c^3 / b^-2
Then we get the answer:
3a^4 c^3
------------
b^-2
I have a picture to clarify!
I hope this helped, let me know if you don't understand! ^.^
40s+2bs+200=number of books needed
if we want 12 books and 8 stalls
b=12
s=8
solve
40(8)+2(12)(8)+200=
320+192+200=
712
needs 712 books
Answer:4p>22
Step-by-step explanation:p is standing for a number
22 needs to be less than four times a number
For example we could fill p in with 8 and it would be 24 which is greater than 22
21 fewer stars than three times a number h
21 - (3 x h)
