Answer:
81a^12/b^12
Step-by-step explanation:
Make everything to the power of 4
3^4=81 (a^3)^4 = a^12 So your numerator will be
81a^12/
Your denominator will be
(b^3)^4=b^12
Thus the answer will be
[tex]\frac{81a^1^2}{b^1^2}[/tex]
you raise each term to the fourth power:
(-3)⁴ = 81
(a³)⁴ = a¹²
(1/b³)⁴ = 1/b¹²
