Q. Which expression is equivalent to (92)6(9^2)^6?\newlineChoices:\newline(A) 198\frac{1}{9^8}\newline(B) 9129^{12}\newline(C) 1912\frac{1}{9^{12}}\newline(D) 989^8
  1. Simplify Expression: Step 11: Simplify the expression using the power of a power rule.\newline(92)6(9^2)^6 means we raise 99 to the power of 22, and then raise the result to the power of 66.\newlineUsing the rule (am)n=amn(a^m)^n = a^{m*n}, we calculate:\newline(92)6=926=912(9^2)^6 = 9^{2*6} = 9^{12}.
  2. Calculate Result: Step 22: Match the result with the given choices.\newlineWe found that (92)6(9^2)^6 simplifies to 9129^{12}.\newlineChecking the choices:\newline(A) 198\frac{1}{9^8}\newline(B) 9129^{12}\newline(C) 1912\frac{1}{9^{12}}\newline(D) 989^8\newlineChoice (B) 9129^{12} matches our calculation.
