Answer:
x=-7
Step-by-step explanation:
Im not sure if what you meant was x cubed, but ill assume it is.
so 7 cubed is 343 so -7 cubed is -343 which cancels out was positive 343 so the answer is x=-7
Answer:
The answer of this question is an imaginary value if we solve the cube root of -343.
Step-by-step explanation:
x^3 + 343 = 0
x^3 = -343
Taking cube root on both sides
∛(x^3) = ∛(-343)
x = ∛(-343)
We can not solve it next because in cube root there is negative sign. If we solve it then it will give us an imaginary value.
