Here we will show you two different procedures you can use to calculate the cube root of 4 divided by the cube root of 85. In other words, we will show you how to calculate ∛4 ÷ ∛85 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:
∛4 ≈ 1.5874
∛85 ≈ 4.3968
1.5874 ÷ 4.3968 ≈ 0.3610
∛4 ÷ ∛85 ≈ 0.3610
Procedure 2
This procedure may be the fastest. Since ∛4 ÷ ∛85 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
4 ÷ 85 ≈ 0.047059
∛0.047059 ≈ 0.3610
∛4 ÷ ∛85 ≈ 0.3610
