__________

here is your answer :







i) Group the three digits starting from left to right i.e. 32 / 768
ii) Since there are two groups, so the cube root will have two digits.
iii) Since, 32 lies between 27 and 64 i.e. 33and 43, therefore smaller of these two will be taken that is 3. So the first digit will be 3.
iv) The second digit of cube root is decided by the second group i.e. 768 which is ending by 8, it means cube root ending in 2.
So, the first digit is 3 and second digit is 2.
Thus the cube root of 32768 is 32.
