Answer:

\frac{27}{98}

Step-by-step explanation:

\frac{4^{-3}\times14^{-7}\times216}{7^{-5}\times8^{-3}}

=\frac{4^{-3}\times7^{-7}\times2^{-7}\times216}{7^{-5}\times2^{-3}\times4^{-3}}

7^{[-7-(-5)]}\times2^{[-7-(-3)]}\times216 (\frac{a^m}{a^n}=a^{m-n})

7^{[-7+5]}\times2^{[-7+3]}\times216

7^{(-2)}\times2^{(-4)}\times216

\frac{1}{7^2}\times\frac{1}{2^4}\times216 (a^{-m}=\frac{1}{a^m})

\frac{1}{49}\times\frac{1}{16}\times216

\frac{1}{49}\times\frac{1}{4}\times54

\frac{1}{49}\times\frac{1}{2}\times27

\frac{27}{98}

\frac{4^{-3}\times14^{-7}\times216}{7^{-5}\times8^{-3}}=\frac{27}{98}
