Question

find the least number that should be added to 2765 them as perfect square. step by step explanation . pls answer .​

Answer 1

Step-by-step explanation:

example-

Find the least number, which must be added to 1825 to make it a perfect square.

Solution :

Step 1 :

Separate the digits by taking commas from right to left once in two digits.

18, 25

When we do so, we get 18 before the comma.

Step 2 :

Now we have to multiply a number by itself such that the product ≤ 18

(The product must be greatest and also less than 18)

The above condition will be met by “4”.

Because 4 ⋅ 4 = 16 ≤ 18

Now this situation is explained using long division

In the above picture, 16 is subtracted from 18 and we got the remainder 1.

Step 3 :

Now, we have to bring down 25 and quotient 4 to be multiplied by 2. So we get 8.

We don't have to continue hereafter.

42 (42) = 1764

43(43) = 1849The given number (1825) is > 422, but less than 432.

From this we come to know that the square root of the given number lies between 42 and 43.

1849 - 1825 = 24

Inorder to convert the given number as the square of 43, we have to add 24.
