To find the product of the expression 7√28√2, we can start by breaking it down step by step.
1. **Evaluate √28**:
We can simplify √28 because 28 can be factored into prime factors:
- 28 = 4 × 7
Since 4 is a perfect square, we can take its square root:
- √28 = √(4 × 7) = √4 × √7 = 2√7
2. **Substituting back**:
Now we replace √28 in the original expression:
- 7√28√2 = 7(2√7)√2
3. **Multiply the constants**:
Now, we can multiply the constants:
- 7 × 2 = 14
So we have:
- 14√7√2
4. **Combine the radicals**:
Next, we can combine the square roots:
- √7√2 = √(7 × 2) = √14
5. **Final product**:
Putting it all together, we get:
- 7√28√2 = 14√14
Thus, the product of the radical expression 7√28√2 simplifies to:
