Estimate \sqrt[3]{20} between two integers.

Question

Estimate
`\sqrt[3]{20}` between two integers.

Answer 1

∛20 is between 2 and 3.

Step-by-step explanation

The question asks us to find the cube root of 20.

∛20

The key to doing this without the calculator is to take the cube of numbers and the one that has 20 in between them is the answer.

1³ = 1

2³ = 8

3³ = 27

We can see that 20 is between 8 and 27.

So,the cube root of 20 has to be betwen 2 and 3.

The other way to do this with the calculator is to actually find the cube root of 20

∛20 = 2.71

Which is between 2 and 3.
