Convert cube root of 421 to square root

Here is the formula and math required to convert the cube root of 421 to an equivalent square root. Before we continue, note that the math symbol for a cube root is ∛, and the math symbol for a square root is √. To convert ∛421 to √, we start by making a cube root (c) to square root (s) formula, like this:

∛c = √s
(∛c)² = (√s)²
(∛c)² = s

Now that we have our formula, we can convert the cube root of 421 to a square root by entering 421 in for c in our formula. Here is the math and the answer:

(∛c)² = s
(∛421)² = s
(∛421)² ≈ 56.1722
∛421 ≈ √56.1722
Cube root of 421 ≈ Square root of 56.1722
