What is the cube root of 647 squared? On this page, we will show you three methods you can use to solve this math problem. However, before we begin, let us show you the mathematical presentation of cube root of 647 squared:
(∛647)²
Method 1:
In this first method, we start by taking the cube root of 647, and then square the result. In other words, we follow the rule of PEMDAS and solve what is inside the parentheses first, before the exponent. Here is the math and the answer:
∛647 ≈ 8.649044
8.649044² ≈ 74.80596
(∛647)² ≈ 74.80596
Method 2:
In the second method, we start by squaring 647 and then take the cube root of the result. This method is possible because of this rule: ∛a × ∛b = ∛(a × b). Here is the math and the answer to do it this way:
647² = 418609
∛207936 ≈ 74.80596
(∛647)² ≈ 74.80596
Method 3:
In the third and final method, we convert the problem to a base with an exponent and solve it. This method is possible because (∛x)² is equal to x raised to the power of 2/3. Here is the math and the answer to do it this way:
(∛647)² = 647²/³
647²/³ ≈ 74.80596
(∛647)² ≈ 74.80596
Bonus:
By popular demand, we have also calculated the simplest radical form of the cube root of 647 squared:
(∛647)² = ∛418609
