Answer 1

No, the number 2,208 is not a perfect square.

Why is 2,208 not a perfect square?
A perfect square is a number that can be expressed as the product of two equal integers.

The only way to accurately calculate if a number is a perfect square is to find the factors. Before we go through the trouble of finding the factors, there is a quick trick you can use to help determine if you need even need to do the extra work.


Try these steps first:

A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square.
Obtain the digital root of the number. The digital root essentially is the sum of all of the digits. If you're lost, don't worry, we'll go over each step in more detail below.
All possible numbers that are a perfect square have a digital root of 1, 4, 7, 9.

Answer 2

Step-by-step explanation:

for these kind of questions we have to find in between what squares, 2208 lies..

so let's take 40^2=1600

50^2=2500

now let's take 45^2=2025

clearly 2208 lies between 45 and 50

now take squares from 45 to 50

45^2=2025

46^2=2116

47^2=2209

48^2=2304

49^2=2401

50^2=2500

now it's easy to predict the nearest perfect square to 2208..

its 2209

now only 1 has to be added to 2208 to become a perfect square..(2208+1=2209)

So answer is 1
