The cube root of a natural number 343 is the value that, when multiplied by itself twice, gives 343. In mathematical terms, this can be represented as ∛343 = x, where x represents the cube root.
To find this value, we need to identify a number that, when multiplied by itself twice, equals 343. In this case, the cube root of 343 is 7, since 7 x 7 x 7 = 343. Therefore, the cube root of 343 is 7.
