Question

Find the cube root of 12167 by groping method

Answer 1

Step-by-step explanation:

Answer. We shall separate 12167 in to groups. 167 ends with 7 and we know that if 7 is at the units place of any perfect cube number then its cube root will have 3 at its units place only. therefore, the digit at the units place of the required cube root is taken as 3.

Answer 2

Answer:

$\sqrt[3]{12167} = 23$

Step-by-step explanation:

3√{12167)

√12_167

Last digit is seven means cube root is 3 then and first 2 digit is 12 means 2×2×2 cube root of 2

hence 8 is below than 12 cube root value is

23
