Explanation:
The question is not clear. So, assuming that the expression you need to simplify is this one:
![(3a^2)^3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/gsfwcnqn74higr2epg905udxpwr4unk17j.png)
You need to remember a property called "Power of a power property". This property states the following:
![(b^m)^n=b^((m*n))=b^((mn))](https://img.qammunity.org/2021/formulas/mathematics/middle-school/98gn7po7xcl8hzjhf24zrq30scoth11b1n.png)
Therefore, you need to apply the Power of a power property explained before, in order to simplify the expression provided in the exercise, multiplying the exponents inside the parentheses by the exponent outside of the parentheses. Then:
![(3a^2)^3=3^((1*3))a^((2*3))=3^3a^6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ewqvud70lzg3ag2mcd6ivicmhu3ngemfd1.png)
Now, you must remember that:
![3^3=3*3*3=27](https://img.qammunity.org/2021/formulas/mathematics/middle-school/2iy3gfw21ty0knensknd4dubominr6r2i9.png)
Finally, you get:
