OpenStudy (misty1212):

OpenStudy (anonymous):

OpenStudy (anonymous):
yes
OpenStudy (misty1212):
ok then \[15^{-5}=\frac{1}{15^5}\]

ok
OpenStudy (misty1212):
\(15^5\)i is a pretty large number so it is probably A
OpenStudy (anonymous):
lol
a isn't a large number... its under 1
OpenStudy (triciaal):
if you really need help you would not repost
OpenStudy (misty1212):
actually none of those answers are correct
i am going to guess that is it really \[5^{-5}\]

since \[5^5=3125\] you have \[5^{-5}=\frac{1}{5^5}=\frac{1}{3125}\]
