Simplify the following expression ?

((-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)

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
