Here we will show you two different procedures you can use to calculate the cube root of 9 divided by the cube root of 81. In other words, we will show you how to calculate ∛9 ÷ ∛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:
∛9 ≈ 2.0801
∛81 ≈ 4.3267
2.0801 ÷ 4.3267 ≈ 0.4808
∛9 ÷ ∛81 ≈ 0.4808
Procedure 2
This procedure may be the fastest. Since ∛9 ÷ ∛81 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
9 ÷ 81 ≈ 0.111111
∛0.111111 ≈ 0.4808
∛9 ÷ ∛81 ≈ 0.4808
