Question

Find the cube root of 12167 by inspection.

Answer 1

12167

The groups are 12 and 167

167 ends with 7 and we know that if 7 is at the unit place of any perfect cube number then it's cube root will have 3 at its units place only. the digit at the units place of required cube root is taken as 3.

Now group 12,

2^3=8 and 3^3=27 also 8<12<27

2 is smaller than 3, therefore 2 is taken as the digit at tens place of the required cube root.

Thus, cube root of 12167 is 23.
