## anonymous one year ago How would you simplify this given expression, assuming that no variable equals 0?

1. anonymous

.

2. anonymous

$\left(\frac{3x^{2n}y^2}{x^ny}\right)^3$

3. anonymous

you can work from the outside in or from the inside out you pick

4. anonymous

How would you do that? Sorry I'm really bad at this.

5. anonymous

first multiply each exponent by 3 to get rid of the 3 outside the parentheses

6. anonymous

don't forget to raise $$3$$ to the power of $$3$$ as well

7. anonymous

you should get $\huge\frac{27x^{6n}y^6}{x^{3n}y^3}$

8. anonymous

next and last step is to subtract the exponents on the like variables

9. anonymous

$\huge 27x^{6n-3n}y^{6-3}$ is a start
