Answer:
I see a lot of answers that make a mistake with the coefficient 3, let’s see step by step:
We have inside the parenthesis “3 power 1” and “x power -2”
(3x−2)3
A value with negative exponent is equivalent to its multiplicative inverse
(3x2)3
We use exponents laws: all exponent inside de parentheses multiply 3
33x2∗3
Finally we have
27x6
