Here we will show you two different procedures you can use to calculate the cube root of 8 divided by the cube root of 81. In other words, we will show you how to calculate ∛8 ÷ ∛81 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
∛81 ≈ 4.3267
2 ÷ 4.3267 ≈ 0.4622
∛8 ÷ ∛81 ≈ 0.4622
Procedure 2
This procedure may be the fastest. Since ∛8 ÷ ∛81 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
8 ÷ 81 ≈ 0.098765
∛0.098765 ≈ 0.4622
∛8 ÷ ∛81 ≈ 0.4622
