dont ask y it just is
OpenStudy (johnweldon1993):
Hint...when you are dividing by a fraction...flip the fraction and turn this into multiplication
\[\large \frac{3x^3}{4y} \times \frac{9y}{x}\]and solve

so just multiply straight across...what do you get?
OpenStudy (anonymous):
27x^3y/4xy ?
OpenStudy (johnweldon1993):
Perfect...so we have
\[\large \frac{27x^3y}{4xy}\]
see anything that can cancel out?
OpenStudy (anonymous):
x and y
OpenStudy (anonymous):
or just ?

y
OpenStudy (johnweldon1993):
Well...the 'y' yes....
\[\large \frac{27x^3\cancel{y}}{4x\cancel{y}}\]
so we have
\[\large \frac{27x^3}{4x}\]
anything else?
OpenStudy (johnweldon1993):
Hint** notice that the top and the bottom have at least 1 'x'
OpenStudy (anonymous):
the x i think
OpenStudy (johnweldon1993):
Right...but notice the top....has 3 'x' ...because
\[\large x^3 = x \times x \times x\] right?
so really what we have is
\[\large \frac{27 x \times x \times \cancel{x}}{4\cancel{x}}\]
which leaves us with
\[\large \frac{27x^2}{4}\]make sense?
