To simplify the expression \( \frac{1}{x} \cdot \frac{1}{x} \cdot \frac{1}{x} \cdot \frac{1}{x} \cdot \frac{1}{x} \cdot \frac{1}{x} \), we can rewrite it as follows:
\[ \left(\frac{1}{x}\right)^6 \]
This expression can be simplified using the property of exponents, which states that \( \frac{1}{a^n} = a^{-n} \). Thus,
\[ \left(\frac{1}{x}\right)^6 = x^{-6} \]
To express this with positive exponents, we can write:
\[ x^{-6} = \frac{1}{x^6} \]
So, the fully simplified expression in exponential form with positive exponents is:
\[ \frac{1}{x^6} \]
