and okay what do you mean @dtan5457

OpenStudy (dtan5457):

Example (6^3)^-5 =6^-15

OpenStudy (mwhit2101):

Ohh

OpenStudy (dtan5457):

the reason why your answers are all in fractions is because

OpenStudy (mwhit2101):

So i could do 7^-15

OpenStudy (dtan5457):

yes, just remember that \[6^{-15}=\frac{ 1 }{ 6^{15} }\]

OpenStudy (dtan5457):
