Q. Which is equal to 1692\frac{1}{6^{92}}?\newlineChoices:\newline(A) 1692-\frac{1}{6^{-92}}\newline(B) 6926^{92}\newline(C) 6926^{-92}\newline(D) 1(6)92-\frac{1}{(-6)^{-92}}
  1. Understand Expression: Understand the given expression 1692\frac{1}{6^{92}}. The expression represents the reciprocal of 66 raised to the power of 9292.
  2. Apply Negative Exponent Rule: Apply the negative exponent rule.\newlineThe negative exponent rule states that am=1ama^{-m} = \frac{1}{a^m}. Therefore, we can rewrite 1692\frac{1}{6^{92}} as 6926^{-92}.
  3. Compare with Choices: Compare the given choices with the transformed expression.\newlineWe have transformed the original expression to 6926^{-92}. Now we need to find the choice that matches this expression.\newline(A) 1692-\frac{1}{6^{-92}} does not match because of the negative sign in front.\newline(B) 6926^{92} does not match because it is the reciprocal of the original expression.\newline(C) 6926^{-92} matches exactly with our transformed expression.\newline(D) 1(6)92-\frac{1}{(-6)^{-92}} does not match because of the negative signs.
