Question

find the positive integers which when multiplied by itself gives 678,976​

Answer 1

let the number be x

ATQ,

$x \times x = 678976 \\ \: \: \: \: \: \: \: \: {x}^{2} = 678976 \\ \: \: \: \: \: \: \: \: x = \sqrt{678976} \\ \: \: \: \: \: \: \: \: x = \sqrt{824 \times 824} \\ hence \: x = 824$

So the number is 824.

You can check it.
