answer= 56 is the cube root of 175616

- 12

EXTENSION METHOD :

Given no.175616

First make pair of three digits from RHS of the no. We get two pairs as

175(2ndpair) and616(1st pair)

Now the unit's place digit of 1st pair i.e.6 gives the one's place of the required cubic root.

Then observe that the 2nd pair lies in between the cubic roots of which two numbers i.e. 5^3=125Here 5 is smaller then 6. Therefore, 5 gives the 10's place no of the required cubic root.

Therefore the cube root of 175616 is 56.
