    \[\frac{ 1 }{ a^2 } = a^{-2}~~and~~ a^x \times a^y = a^{x+ y}\]

    \[\frac{ 1 }{ 12^{7} } = 12^{-7}\]

    a^x / a^y =a^(x-y)

    remember \[\frac{ 1 }{ a } = a^{-1}\]

    there's no negative exponents .

    @yinkim52001 remember \[\frac{ 1 }{ a } = a^{-1}\]

    You never leave your answers with negative exponents unless it's called for. Therefore \[\frac{1}{12^4} = \frac{1}{12\cdot 12\cdot 12\cdot 12}\] Whatever that is is your answer.

    12^4 is the answer right?

    @Jhannybean its asking to just simplfy it ..... so i think we may just write in exponential form

    You can have various simplifications @rishavraj either in positive exponential form, fully expanded form, or even negative exponent form. They would all be correct.

    \[\frac{12^{-3}}{12^7} = 12^{-4} =\frac{1}{12^4} = \frac{1}{20736}\] TRy solving the next one yourself @Spring98
