Question

Find the least number which must be subtract from 402 so as to get a perfect square. Also find the square root of the perfect square so obtained ?​

Answer 1

Answer:

Step-by-step explanation:

Closest perfect square = 400

Thus, 402 - 400 = 2

Therefore 2 should be subtracted from 402 to get perfect square

Square root of perfect square = √400 = ±20

Answer 2

Answer:

$Here, we get the remainder 2. Therefore 2 must be subtracted from 402 to get a perfect square. Hence, the square root of 400 is 20.}$
