Answer:

  • 5√2

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
