Answer:

x=4

Step-by-step explanation:

Cross-multiply to simplify:

\frac{x}{12}=\frac{3}{9},\\9x=12\cdot 3,\\9x=36

Divide both sides by 4 to isolate x:

x=\frac{36}{9}=\boxed{4}

What would this be using a positive exponent?
tatuchka [14]

1 / 9^4 and 1 / 6^3

This is because in order to make a negative exponent into a postive exponent, you need to make it into a fraction, 1 as the top number, and the negative exponent as a postive one.

For example, 6^-3 becomes 1 / 6^3.

I hope I helped.
