Explanation:
Given:
- 3i^+4j^+5k^
To Find:
- Numerical value
Solution:
As we know that,
- ai^+bj^+ck^ = √(a² + b² + c²)
So, By using this let's find the numerical value of 3i^+4j^+5k^
⇒ 3i^+4j^+5k^
⇒ √(3² + 4² + 5²)
⇒ √(9 + 16 + 25)
⇒ √(50)
⇒ √(2 × 5 × 5)
⇒ 5√2
∴ Numerical value of 3i^+4j^+5k^ = 5√2
