Question

plz plz someone give the answer.​

Answer 1

Step-by-step explanation:

Here,

the smallest number of four digit is 1000.

then,

$the \: square \: of \: 31 \: is$

$= {31}^{2}$

$= 961$

so, square number greater than square of 31 is the perfect square number of the least no. of four digit as 31² is the greatest square no. of three digit...

therefore,

$the \: least \: perfect \: square \: number \: of \: four \: digit \: is$

$= {32}^{2}$

$= 1024$

which is 24 greater than 1000....

$and \: the \: square \: root \: of \: 1024$

$= 32$

thanks a lot...
