(x+7)^(2/3) = ((x +7)^(1/3))^2 it implies that LHS always has to be positive since it is a square. therefore there is no value of x that satisfies the equation.

No solutions exist.
(x+7)^(2/3) = ((x+7)^2)^(1/3).
Since a square is always positive, if you raise the result to the power (1/3) it is still positive.
It will never be -4, so no solutions exist.
∛(〖(x+7)〗^2 ) = -4
〖(∛((x+7)^2))〗^3= (-4)^3
(x+7)^2= -64
x^2+14x+49=-64
x^2+14x+117=0
you will have to use the quadratic equation to solve for ‘x’
a = 1; b = 14; c = 117
hope this helps

(x+7)^(2/3)=-4
(x+7)=(-4)^(3/2)
x+7=-8i
x=-7 -8i
or did you need a awnser in a reel vector space well too bad there isn't one
