Answer:402

Step-by-step explanation:We know that, if we subtract the remainder from the number, we get a perfect square.

Here, we get the remainder 2. Therefore 2 must be subtracted from 402 to get a perfect square.

[tex]402 – 2 = 400 [/tex]

square root of 400,

[tex] \sqrt{400} = 20[/tex]

so the least number which must be subtracted is
