okay so multiply the top first and by doing so add the powrs.
OpenStudy (anonymous):
so x^12/4
over x^1/4
OpenStudy (raffle_snaffle):
now when you divide you subtract the powers
OpenStudy (anonymous):
ok ok so it would be 11/4???

reduce 12/4
OpenStudy (raffle_snaffle):
before you divide
OpenStudy (anonymous):
x^3 then divide by x^1/4?
OpenStudy (raffle_snaffle):
yeah so when you divide you subtract the powers
OpenStudy (anonymous):
since 3 is a whole number it would be 3/1, then subtract 1/4 so its 2/4=1/2 right?

sigh let me to this on paper
OpenStudy (raffle_snaffle):
are you sure the answer is x^4
OpenStudy (raffle_snaffle):
I think your solution is wrong.
OpenStudy (anonymous):
its actually a tue or false question whether it equals x^4 or not....
OpenStudy (raffle_snaffle):
well it's false. Lol

hahaha yeah but what would i do after i reduced 12/4 to 3
OpenStudy (raffle_snaffle):
basically when you have variables with rational powers you that are multi you add the powers and division you subtract.
OpenStudy (raffle_snaffle):
bad english... when mult you add power and division you subtract
OpenStudy (raffle_snaffle):
so after you reduce you have x^3/x^1/4 now you sub powrs
OpenStudy (raffle_snaffle):
so you would get x^11/4
