Answer 1

Answer: $27a^6$

Step-by-step explanation:

The question is not clear. So, assuming that the expression you need to simplify is this one:

$(3a^2)^3$

You need to remember a property called "Power of a power property". This property states the following:

$(b^m)^n=b^{(m*n)}=b^{(mn)}$

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:

$(3a^2)^3=3^{(1*3)}a^{(2*3)}=3^3a^6$

Now, you must remember that:

$3^3=3*3*3=27$

Finally, you get:

$=27 a^6$
