Answer

(a) no (b) yes

Work Step by Step

(a) Using $x=-1$, we get: Left side: $2(-1)^{1/3}-3=2(-1)-3=-2-3=-5$ Right side: $1$ The sides do not match, so $x=-1$ is not a solution. (b) Using $x=8$, we get: Left side: $2(8)^{1/3}-3=2(2)-3=4-3=1$ Right side: $1$ The sides match, so $x=8$ is a solution.
