Hello

I am simplifying this right????

$$(\frac{ab^2c^{-3}}{2a^3b^{-4}})^{-2}$$

$$\frac{4a^4c^{6}}{b^{12}}$$

just remember the simple rules: if its a negative exponent flip the fraction, and if you have a product under the exponent each part is raised to the power separately.

ofcourse you can always just plug it into a calculator if you dont trust yourself at all...
