-27 by it self?
OpenStudy (danjs):
one twenty seventh
OpenStudy (anonymous):
so just take away the negative sign
OpenStudy (danjs):
you can move bases raised to powers to the other side of the fraction, and that will change the sign on the power.
\[3^{-3} = \frac{ 1 }{ 3^3 } = \frac{ 1 }{ 27 }\]
OpenStudy (danjs):
try
\[\frac{ 3^{-10 }}{ 5^{-4} } = \]

sorry got to run... change the sign on the power when you change the side of the fraction the base is on...like this..
\[\frac{ 3^{-10 }}{ 5^{-4} } = \frac{ 5^4 }{ 3^{10} }\]
