Here we will show you two different procedures you can use to calculate the cube root of 20 times the cube root of 33. In other words, we will show you how to calculate ∛20 × ∛33 two different ways.
Procedure 1
This is the straightforward approach, where you first find the cube root of each number and then multiply the results. Here's how it looks:
∛20 ≈ 2.7144
∛33 ≈ 3.2075
2.7144 × 3.2075 ≈ 8.7066
∛20 × ∛33 ≈ 8.7066
Procedure 2
This procedure is often the quickest. Since ∛20 × ∛33 is equivalent to ∛(34 × 56), you can first multiply the numbers and then find the cube root of the product. Here's the step-by-step:
20 × 33 = 660
∛660 ≈ 8.7066
∛20 × ∛33 ≈ 8.7066
