Use the method to write the perfect square integers between 1 and 80 inclusive

Inclusive means including 1 and 80

ok so we know that 1^2=1 so 1 is a perfect square

just go up and square them untill 80 and the results is your answers

2^2=4, 4 is another

3^3=9

4^2=16

5^2=25

6^2=36

7^2=49

8^2=64

9^2=81 which is over

so the perfect squares from 1 to 80 are

1,4,9,16,25,36,49,64
