Here we will show you two different procedures you can use to calculate the cube root of 7 divided by the cube root of 81. In other words, we will show you how to calculate ∛7 ÷ ∛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:
∛7 ≈ 1.9129
∛81 ≈ 4.3267
1.9129 ÷ 4.3267 ≈ 0.4421
∛7 ÷ ∛81 ≈ 0.4421
Procedure 2
This procedure may be the fastest. Since ∛7 ÷ ∛81 is the same as ∛(34/56), you can first divide the numbers, and then find the cube root of the quotient, like this:
7 ÷ 81 ≈ 0.086420
∛0.086420 ≈ 0.4421
∛7 ÷ ∛81 ≈ 0.4421
