Answer: [tex]1[/tex] and [tex]81[/tex].
Step-by-step explanation:
Since, we have number [tex]9[/tex] with help of which we have to find a square.
If we divide 9 by 9 then we will obtain 1 which is itself a square.
That is, [tex]\frac{9}{9} = 1[/tex]
Now, If we multiply 9 by itself we obtain 81, which is the square of 9.
That is, [tex]9\times 9 = 81[/tex]
Note: We can also make other squares by using number 9.
