Answer 1

Heya....


Your answer with full explanation is here....


First remember this point......

To check whether a number is perfect square or perfect cube, we can do this by simply looking at the unit place digit.

Here, we will not talk about squares.

Let's move to the question...

POINT TO REMEMBER :-

The cubes of different unit digits ends with unit place digit.
e.g. 
Cube of a number having 0 as unit place digit ends with 000 as unit place digit.
Cube of a number having 1 as unit place digit ends with 1 as unit place digit.
Cube of a number having 2 as unit place digit ends with 8 as unit place digit.
Cube of a number having 3 as unit place digit ends with 7 as unit place digit.
Cube of a number having 4 as unit place digit ends with 4 as unit place digit.
Cube of a number having 5 as unit place digit ends with 5 as unit place digit.
Cube of a number having 6 as unit place digit ends with 6 as unit place digit.
Cube of a number having 7 as unit place digit ends with 3 as unit place digit.
Cube of a number having 8 as unit place digit ends with 2 as unit place digit.
Cube of a number having 9 as unit place digit ends with 9 as unit place digit.

Now given in the question.

44447.

the unit place digit is 7. So we can say that the cube of this digit will have 3 as ones place digit.

Hope it helps.........
