Question

find the cube root of the following 64×343​

Answer 1

Answer:

343 has got a factor of (4≥X≤n)

Where n is the larger number preceding the cube root of 343 . This implies that the cube root should not be less than 4 too.

= ³√64 / ³√343

= X is between 4 and n

Obviously n is beyond 10, 9, 8 and 7.5

And X is not beyond 7.5, 8, 9, 10……..

10³= 1000

While 4³ = 64

Answer is 7.
