Question

square of a number is 2 square root 12 which is the number

Answer 1

Let the number be x.

A/Q,

${x}^{2} = 2 \sqrt{12} \\ {x}^{2} = \sqrt{48}$
Squaring both sides,
${x}^{4} = 48 \\ x = \sqrt[4]{48} \\ x = \sqrt[4]{2 \times 2 \times 2 \times 2 \times 3} \\ x = 2 \sqrt[4]{3}$

Hope it helps!
