Question

UpStudy AI · Accepted Answer

To evaluate the expression $$ \sqrt[3]{343} $$, let's break it down step by step.

### Step 1: Understand the Cube Root
The cube root of a number $$ x $$ is a value that, when multiplied by itself three times, gives $$ x $$. In mathematical terms:
$$ \sqrt[3]{x} = y \quad \text{if and only if} \quad y^3 = x $$

### Step 2: Apply to $$ \sqrt[3]{343} $$
We need to find a number $$ y $$ such that:
$$ y^3 = 343 $$

### Step 3: Find the Appropriate Value
Let's test $$ y = 7 $$:
$$ 7^3 = 7 \times 7 \times 7 = 343 $$
Since $$ 7^3 = 343 $$, it follows that:
$$ \sqrt[3]{343} = 7 $$

### Conclusion
The correct answer is:

**C. 7**
The cube root of 343 is 7.
