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,
[tex]\sqrt{x} = \sqrt{6400}\\=80[/tex]
Step 2:
Divide the result from step 1 by 10,
[tex]\frac{\sqrt{x}}{10}=\frac{80}{10}=8[/tex]
Step 3:
Take cube root of the resultant number from step 2,
[tex]\sqrt[3]{x}=\sqrt[3]{8}=2[/tex]
Step 4:
Multiply the resultant number from step 3 by 0,
[tex]2\times 0=0[/tex]
Hence converted.
