Answer 2

Answer:

(1) 6 (2) 3 (3)5 (4)0

Step-by-step explanation:

Unit digit of the cube of a number would be the unit digit obtained by taking the cube of the digit in unit's place of that number.

For example, suppose the number is 36,

Unit digit of cube of 36 can be found out by checking the unit digit of cube of 6 i.e. 6x6x6 = 256.

Similarly for number 17, 7x7x7 = 343

Any power of a number whose unit digit is 5 or 0 will always have 5 or 0 respectively as its unit's place.
