Here we will show you two different procedures you can use to calculate the cube root of 5 divided by the cube root of 21. In other words, we will show you how to calculate ∛5 ÷ ∛21 two different ways.
Procedure 1
This may be the most obvious procedure, where you first calculate the cube root of each number, and then divide the result, like this:
∛5 ≈ 1.71
∛21 ≈ 2.7589
1.71 ÷ 2.7589 ≈ 0.6198
∛5 ÷ ∛21 ≈ 0.6198
Procedure 2
This procedure may be the fastest. Since ∛5 ÷ ∛21 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
5 ÷ 21 ≈ 0.238095
∛0.238095 ≈ 0.6198
∛5 ÷ ∛21 ≈ 0.6198
