OpenStudy (swissgirl):

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

OpenStudy (swissgirl):

\( \huge { 1 \over 3}\)

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 \( \huge {y\over y^2} \) =?

OpenStudy (anonymous):

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: \( \large {1\over 3} *{1 \over y}*x = \huge {x \over 3y} \)

OpenStudy (swissgirl):

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

OpenStudy (anonymous):

hahah yea just summer and a year of non algebra just makes you forget everything
