Question

Ingresa en la calculadora un numero de 4 cifras.¿como harias para convertir ese numero en 0 usando exactamente cuatro cuentas?

Answer 1

Answer:

Multiply the last value by 0.

Step-by-step explanation:

The question is:

Enter a 4-digit number into the calculator. How would you convert that number to 0 using exactly four accounts?

Solution:

Consider any 4-digit number.

Let the number be, x = 6400.

Convert 6400 to 0 as follows:

Step 1:

Take square root of the number, x = 6400,

$\sqrt{x} = \sqrt{6400}\\=80$

Step 2:

Divide the result from step 1 by 10,

$\frac{\sqrt{x}}{10}=\frac{80}{10}=8$

Step 3:

Take cube root of the resultant number from step 2,

$\sqrt[3]{x}=\sqrt[3]{8}=2$

Step 4:

Multiply the resultant number from step 3 by 0,

$2\times 0=0$

Hence converted.
