Question

write 9square as the sum of two conaecutive posite number ​

Answer 1

We know that, 9square = 81

Let one number be 'y'

Then, other number = (y+1)

ATQ; y+y+1=81

     =>2y=80

     =>y= 80/2=40

Therefore, the first number is 40

                  the other number is 40+1=41

So, the numbers are 40 & 41
