What is the product of \(\frac{27}{5^1}\)(3)-3 and \(\frac{(1)^{-1}}{5}\)?
A
5
B
3
C
1
D
\(\frac{1}{25}\)
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
\(\frac{27}{5^1}\)(3)-3 x \(\frac{(1)^{-1}}{5}\) = \(\frac{27}{5}\) x \(\frac{1}{3^3}\) x \(\frac{1}{\frac{1}{5}}\)
= \(\frac{27}{5}\) x \(\frac{1}{27}\) x \(\frac{1}{5}\)
= \(\frac{1}{25}\)
