Question

What value for x could make the sentence true?
x3 = 343

Answer 1

1,029,49,21,7

Answer 2

which option is correct

Answer 3

is that 3 times x, or is that x^3? If it's x^3, then you need to cube root each side [\sqrt[3]{x ^{3}}=\sqrt[3]{343}\] to simplify/solve the equation.
The answer would then be 7, as \[7\times7\times7=343\] which is to say \[7^{3}=343\]

Answer 4

\[\sqrt[3]{x^{3}}=\sqrt[3]{343}\]
