Math Question. Please explain!

OpenStudy (anonymous):

\[\frac{ 4xy ^{-2} }{ 12x ^{1/3}y ^{-5} }\]

imqwerty (imqwerty):

x^a/x^b = x^(a-b)

OpenStudy (anonymous):

So the next step would look like this?\[\frac{ x ^{\frac{ 2 }{ 3 }} }{ 3 y ^{7}}\]

OpenStudy (skullpatrol):

Look at the exponent of y again please.

OpenStudy (anonymous):

Was that suppose to be -7?

OpenStudy (mathmath333):

i mean y should be in numerator

OpenStudy (phi):

follow the rule y^(-2 - - 5)

OpenStudy (skullpatrol):

-2 - (-5) = ?

imqwerty (imqwerty):

y^(-2)/y^(-5) = y^(-2-(-5))

OpenStudy (anonymous):

\[\frac{ x ^\frac{ 2 }{ 3 }y ^{3} }{ 3 }\]

OpenStudy (skullpatrol):

Correct :-)

OpenStudy (mathmath333):

its corect

OpenStudy (anonymous):

Okay thanks!

imqwerty (imqwerty):
