To simplify the expression 6q^0r^-3/3q^-1r^-1 using positive exponents, we can apply the rules of exponents. Remember that any number raised to the power of 0 is equal to 1, and when we have a negative exponent, we can move it to the denominator by changing the sign.
So, the expression becomes:
(6 * 1 * 1)/(3 * q^1 * r^1 * r^3)
Simplifying further, we get:
6/(3qr^4)
