Answer 1

Step-by-step explanation:

1) 16 Yes

= 11 = Odd Number.

3) 256 Yes

= 16² = 16×16 = 256

= 16 = Even Number

4) 169 No

= 13² = 13×13 = 169

= 13 = Odd Number

5) 324 Yes

= 18² = 18×18 = 324

= 18 = Odd Number

6) 400 Yes

= 20² = 20×20 = 400

= 20 = Even Number

7) 676 Yes

= 26² = 26×26 = 676

= 26 = Even Number

8) 841 No

= 29² = 29×29 = 841

= 29 = Odd Number

9) 333 No, not a perfect square.

10) 225 No
