Here we will show you two different procedures you can use to calculate the cube root of 8 divided by the cube root of 20. In other words, we will show you how to calculate ∛8 ÷ ∛20 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:
∛8 = 2
∛20 ≈ 2.7144
2 ÷ 2.7144 ≈ 0.7368
∛8 ÷ ∛20 ≈ 0.7368
Procedure 2
This procedure may be the fastest. Since ∛8 ÷ ∛20 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
8 ÷ 20 = 0.4
∛0.4 ≈ 0.7368
∛8 ÷ ∛20 ≈ 0.7368
