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 first rewrite it using powers.
Since we are multiplying six fractions of \( \frac{1}{x} \), we can express this as:
\[ \left( \frac{1}{x} \right)^6 \]
Using the properties of exponents, we can simplify \( \left( \frac{1}{x} \right)^6 \) to:
\[ \frac{1^6}{x^6} = \frac{1}{x^6} \]
Now, to express it with positive exponents, we can rewrite \( \frac{1}{x^6} \) as:
\[ x^{-6} \]
However, since the instructions require that we write it in exponential form with positive exponents only, we express the negative exponent according to the guidelines:
\[ \frac{1}{x^6} \]
So, the final simplified form of the expression in positive exponent form is:
\[ \frac{1}{x^6} \]
