Question

$1 \times 1 = 1 \sqrt[]{?}$

Answer 1

Let question will be replaced with x,


$1 \times 1 = 1 \sqrt{x} \\ \\ \\ 1 = \frac{1 \times \sqrt{x} }{1} \\ \\ \\ 1 = \sqrt{x} \\ \\ \\ {1}^{2} = x \\ \\ \\ 1 \times 1 = x \\ \\ \\ 1 = x$




Hence, question will be replaced with 1

Answer 2

$\textbf {Your answer !!}$

$let \: the \: number = a\\ \\ the \: equation \: becomes.... \\ \\ = > 1 \times 1 = 1 \sqrt{a} \\ \\ = > \frac{1 \times 1}{1} = \sqrt{a} \\ \\ = > \frac{1}{1} = \sqrt{a} \\ \\ = > 1 = \sqrt{a} \\ \\ = > {(1)}^{2} = a \\ \\ = 1 \times 1 = a \\ \\ = > 1 = a$

$\textbf {Hence, the required number = 1}$
