Answer:

4

Explanation:

El número que elevado al cuadrado y multiplicado por 2 es igual a 32 es el número 4.

Si decimos que el número pensado es X, tenemos que:

X elevado al cuadrado y  multiplicado por 2 es igual a 32.

Entonces:

X² × 2 = 32

2 X² = 32

X² = 32/2

X² = 16

X = \sqrt{16}16

X = 4
