What will be the unit digit of the cube of a number ending with 9 ?

9

Step-by-step explanation:

If I’m understanding you correctly, the answer would be nine.  Any number with a 9 in the one’s place (unit digit) would still have a nine in that place after being cubed.

29³=24,389

69³=328,509

Step-by-step explanation:

unit digit of cube of any number will be the unit digit of its last digit

the unit digit of the cube of a number ending with 9 is 9

ex : unit digit of 29³= unit digit of 9³=unit digit of 729 =9

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
