Find the cube of :
`3/7`

Answer

To find the cube of \( \frac{3}{7} \), we will follow these steps:

### Step 1: Write the expression for the cube
We need to find \( \left( \frac{3}{7} \right)^3 \).

### Step 2: Apply the property of exponents
Using the property of exponents, we can write:
\[ \left( \frac{3}{7} \right)^3 = \frac{3^3}{7^3} \]

### Step 3: Calculate \( 3^3 \)
Now, we calculate \( 3^3 \):
\[ 3^3 = 3 \times 3 \times 3 = 27 \]

### Step 4: Calculate \( 7^3 \)
Next, we calculate \( 7^3 \):
\[ 7^3 = 7 \times 7 \times 7 = 343 \]

### Step 5: Combine the results
Now we can combine the results from Steps 3 and 4:
\[ \left( \frac{3}{7} \right)^3 = \frac{27}{343} \]

### Final Answer
Thus, the cube of \( \frac{3}{7} \) is:
\[ \frac{27}{343} \]
