# Check whether the number formed by concatenating two numbers is a perfect square or not in Python

Suppose we have two numbers x and y. We have to concatenate them and check whether the resultant number is perfect square or not.

So, if the input is like x = 2 y = 89, then the output will be True as after concatenating the number will be 289 which is 17^2.

To solve this, we will follow these steps −

• first_num := x as string
• second_num := y as string
• res_num := concatenate first_num and second_num then convert to integer
• sqrt_val := integer part of square root of(res_num)
• if sqrt_val * sqrt_val is same as res_num, then
• return True
• return False

Let us see the following implementation to get better understanding −

## Example Code

Live Demo

from math import sqrt

def solve(x, y):
first_num = str(x)
second_num = str(y)
res_num = int(first_num + second_num)

sqrt_val = int(sqrt(res_num))

if sqrt_val * sqrt_val == res_num:
return True
return False

x = 2
y = 89
print(solve(x, y))

## Input

2, 89


## Output

True
