Answer 2

Step-by-step explanation:

68)3 :

I: 63 | 3. 62 . 8 | 3. 6 . 82 | 83

II: 216 | 864 | 1152 | 512

III:= 314 984 1203 512

(Kept rightmost digit of each part from the right-hand side and Carried forward extra digits to the previous left part)

Start from the right side, in 512; 2 will be written and 51 will be carried 1152.

Then 1152 + 51 = 1203. Now, 3 will be written and 120 carry forward to the 864.

It will be 864 + 120 equals 984. Again, 4 will be written and 98 will be carried forward.

Finally, 216 + 98 is 314. Combining all, the cube of 68 is 314432.
