5^-2 - 5^-1 / 5^-2 + 5^0
OpenStudy (anonymous):
5^-2 = 1 / 5^2 = 1/25
5^-1 = 1 / 5^1 = 1/5
5^0=0
So what you have is,
\[\frac{1/25-1/5}{1/25+1}\]
OpenStudy (anonymous):
can you take it from here, or in need more help ?
OpenStudy (anonymous):
I meant 5^0=1
OpenStudy (anonymous):

OpenStudy (anonymous):
is it possible to do the question using exponent laws , instead of converting the numbers to fractions??
OpenStudy (anonymous):
well, not really... not in this case.
OpenStudy (anonymous):
yea i agree its not really possible but no.
OpenStudy (anonymous):
\[\frac{1/25-1/5}{1/25+1}\]
\[\frac{1/25-5/25}{1/25+25/25}\]
\[\frac{-~4/25}{26/25}\]
\[\frac{-~4}{26}\]
\[-\frac{~2}{13}\]
