Question

Which of the following is the closet approximation to 3√20?A) 3B) 5C) 2D) 4

Answer 1

The given expression is:

$\sqrt[3]{20}$

This can also be written as:

$20^{(\frac{1}{3})}$

The result = 2.71

Since 7 is greater than 5, it will become 0 and add 1 to 2 to become 3

Therefore, the closest approximation is 3
