6) Write with positive exponents: [ 3-3 a-2 b5

c-3 d-4]

To write the expression with positive exponents, we need to move any terms with negative exponents to the opposite side of the fraction and change the exponents from negative to positive.

Let's rewrite the expression:

\[3^{-3} \cdot a^{-2} \cdot b^5 \cdot c^{-3} \cdot d^{-4}\]

To move terms with negative exponents to the opposite side of the fraction, we can take the reciprocal of each term:

\[\frac{1}{3^3} \cdot \frac{1}{a^2} \cdot b^5 \cdot \frac{1}{c^3} \cdot \frac{1}{d^4}\]

Now, let's change the exponents from negative to positive:

\[\frac{1}{3^3} \cdot \frac{1}{a^2} \cdot b^5 \cdot \frac{1}{c^3} \cdot \frac{1}{d^4}\]

Simplifying this expression further is not possible without specific values for a, b, c, and d.
