Answer 2

Answer:

58

Step-by-step explanation:

• Make groups of 3 digits, starting from the right: 195 (second group), 112 (first group)
• Since the last digit of the first group is 2, the last digit of the cube root would be 8. Because $8^{3}$ = 512, $18^{3}$ = 5832, $28^3$ = 21952

• The last digit of the second group is 5. Therefore, we take

             $5^3 = 125\\6^3 = 216$

• 125 < 195 < 216 = $5^3 < 195 < 6^3$.
• Take the smaller number, 5, to be the first digit of the cube root.
• The cube root of 195112 is therefore 58.
