Question

What smallest number should be added to 22 to make it a perfect square?

Answer 1

Answer:

3 must be added to 22 to make it a perfect square

Answer 2

Answer:

FIRST METHOD:::::

Step-by-step explanation:

Let’s suppose that 17=a.

So,20=a+3 ,23=a+6, 26=a+9

Now,17x20x23x26

=a(a+3)(a+6)(a+9)

=a(a+9)(a+3)(a+6)

=(a^2+9a)(a^2+9a+18)

=(a^2 +9a+9–9)(a^2+9a+9+9)

=(a^2+9a++9)^2—(9)^2

So to get a perfect square, now we need to neutralize the 9^2 portion

Hence, we must add 81 . So 81 is the answer
