lol
OpenStudy (anonymous):
\[\sqrt[9]{x}^7\div \sqrt[9]{x}^5\]
OpenStudy (anonymous):
this time subtract the exponents
\[\frac{7}{9}-\frac{5}{9}\] the denominators are the same so it is easy to subtract
OpenStudy (anonymous):
or you could note that
\[\large \frac{\sqrt[9]{x^7}}{\sqrt[9]{x^5}}=\sqrt[9]{\frac{x^7}{x^5}}=\sqrt[9]{x^{7-5}}=\sqrt[9]{x^2}\]

why would you turn into a pumpkin what @satellite73
OpenStudy (anonymous):
a cindarella reference that is all

k this bud's for you
what is \[\frac{4}{5}-\frac{1}{3}\]?
OpenStudy (anonymous):
hint, it is not \(\frac{3}{2}\)
OpenStudy (anonymous):
7/15?
OpenStudy (anonymous):
yeah thats what i had 7/15
OpenStudy (anonymous):
then you win \[x^{\frac{7}{15}}\] or if you prefer
\[\sqrt[15]{x^7}\]

the 3/7 is the exponent for x^34
OpenStudy (anonymous):
this time compute
\[\frac{3}{4}\times \frac{3}{7}\]
OpenStudy (anonymous):
much easier to multiply fractions, just multiply
OpenStudy (anonymous):
9/28
OpenStudy (anonymous):
let me know when you get
\[\frac{9}{28}\]

OpenStudy (anonymous):
so x^9/28 or....
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
or
\[\large \sqrt[28]{x^9}\] if you like
OpenStudy (anonymous):
i seee i seeee

oh trust me i have one
OpenStudy (anonymous):
k take your time and hurry up
OpenStudy (anonymous):
simplify the expression
\[3\div(5x)^{-2}\]
OpenStudy (anonymous):
\[\frac{3}{(5x)^{-2}}=3\times (5x)^2=75x^2\]
