Simplify the following expression ?

Answer:
i dunno sorry
Step-by-step explanation:
I think what you have to do is related to PEMDAS
Answer:
((-8x^3)/27)
Step-by-step explanation:
(3^-3x^-3/-2x^-6)
When the expression looks like this (x^n)^s you multiply the exponents so
x^(n*s)
Work:
3^-3=(1/27) -2^-3= (-1/8)
((1/27)x^(-3))/((-1/8)x^(-6))
Then when dividing you subtract the exponents: -3-(-6)=3
((-8x^3)/27)
