To simplify the expression \( 13^{-6} \div 13 \div 14^{-2} \), we follow these steps:
-
Rewrite the division as multiplication by the reciprocal:
\[ 13^{-6} \div 13 = 13^{-6} \times 13^{-1} \]
This simplifies to:
\[ 13^{-6 - 1} = 13^{-7} \]
-
Now, rewrite the division by \( 14^{-2} \) as multiplication:
\[ 13^{-7} \div 14^{-2} = 13^{-7} \times 14^{2} \]
-
Combine the expression:
\[ 13^{-7} \times 14^{2} = \frac{14^{2}}{13^{7}} \]
-
Finally, we present the answer in exponential form with positive exponents:
\[ \frac{14^2}{13^7} \]
Thus, the simplified expression is:
\[ \frac{14^{2}}{13^{7}} \]
