Official Solution:
Which of the following is equivalent to \(\frac{(\frac{1}{9})^{-9}(\frac{1}{27})^{-3}}{(\frac{1}{3})^{-27}}\)?
A. \(\frac{1}{3}\)
B. \(3^{-54}\)
C. \(1\)
D. \(3\)
E. \(3^{54}\)
\(\frac{(\frac{1}{9})^{-9}(\frac{1}{27})^{-3}}{(\frac{1}{3})^{-27}}=\)
\(=\frac{(\frac{1}{3^2})^{-9}(\frac{1}{3^3})^{-3}}{(\frac{1}{3})^{-27}}=\)
\(=\frac{(\frac{1}{3})^{-18}(\frac{1}{3})^{-9}}{(\frac{1}{3})^{-27}}=\)
\(=(\frac{1}{3})^{-18}(\frac{1}{3})^{-9}(\frac{1}{3})^{27}=\)
\(=(\frac{1}{3})^{-18-9+27}=\)
\(=(\frac{1}{3})^{0}=\)
\(=1\)

\((1/9)^{-9}*(1/27)^{-3} / (1/3)^{-27}\)
=\(9^{9}*27^{3}/3^{27}\)
= \(3^{18}*3^{9}/3^{27}\)
= \(3^{27}/3^{27}\)
=1
=\(9^{9}*27^{3}/3^{27}\)
= \(3^{18}*3^{9}/3^{27}\)
= \(3^{27}/3^{27}\)
=1

\(\frac{(\frac{1}{9})^{-9}*(\frac{1}{27})^{-3}}{(\frac{1}{3})^{-27}}\)
\(\frac{9^9 * 27^3 }{ 3^{27}}\)
\(\frac{3^{18} * 3^9 }{ 3^{27}}\)
\(\frac{3^{27}}{3^{27}}\)
\(3^0\)
\(1\)
ANSWER C
