so we can do everything one step at a time
OpenStudy (swissgirl):
the numbers and then the x's and then the y's
OpenStudy (swissgirl):
so \(\huge {3 \over 9} \) can be reduced to?
OpenStudy (anonymous):
yes 1/2

\( \huge { 1 \over 3}\)
OpenStudy (anonymous):
or that
OpenStudy (swissgirl):
now we know that when dividing exponents if they have the same base you keep the base and subtract the exponents
So \( \huge { x^2 \over x} \) =?
OpenStudy (anonymous):
x
OpenStudy (swissgirl):
yes and \( \huge {y\over y^2} \) =?

y
OpenStudy (swissgirl):
\( \huge {y^1 \over y^2} \)
so that wld be 1-2=-1
so our answer wld be \(y^{-1}\)
OpenStudy (swissgirl):
\( \large y^{-1}={1 \over y} \)
OpenStudy (swissgirl):
soooo all in allll our solution shld look as follows:
\( \large {1\over 3} *{1 \over y}*x = \huge {x \over 3y} \)

hahaha like once you get it u dont have to do all these steps. Liek you just do it in ur brain
