Cool shortcut for cubing 12 cube shortcut assume 1 to be 'a' 2 to be 'b' Expand it for a+b whole cube and write it as 1|6|12|8 Now take 8 as the last digit 2 as the second last c/f 1 add it to 6 so third last digit is 7 and the first digit as no remainder is there it would be 1 so boom 🔥 1728 = 12^3

12 cube shortcut
assume 1 to be 'a' 2 to be 'b'
Expand it for a+b whole cube and write it as
1|6|12|8
Now take 8 as the last digit 2 as the second last c/f 1 add it to 6 so third last digit is 7 and the first digit as no remainder is there it would be 1 so
boom 🔥
1728 = 12^3
did it in my head let's go
Took about 5 seconds to do in my head
I did upto third step.myself then I don't have paper and pen to multiply so😅
