Step-by-step explanation:

3⁰ = 1                    number in once place = 1

3¹ = 3                    number in once place = 3

3² =9                    number in once place = 9

3³ =27                  number in once place = 7

3⁴ =81                  number in once place = 1

3⁵ =243                number in once place = 3

3⁶ =729                number in once place = 9

so, the the number in once place is recurring after 4

{0, 4, 8, ........}For 4n, number in once place = 1

{1, 5, 9, .........}For 4n+1, number in once place = 3

{2, 6, 10,.......}For 4n+2, number in once place = 9

{3, 7, 11,.........}For 4n+3, number in once place = 7

here, 2020 = 4×505 ; (4n) : so the last digit or number inn once place is 1
