Math 8 Q2 (Pre-Algebra) / Roots and Irrational Numbers

(5√19) x (6√2)

Answer 1

To simplify the given expression, (5√19) x (6√2), we can multiply the numbers outside the square roots together and the numbers inside the square roots together.

(5√19) x (6√2) = 5 * 6 * √19 * √2

Multiplying the numbers outside the square roots:

5 * 6 = 30

Now, let's multiply the numbers inside the square roots:

√19 * √2 = √(19 * 2) = √38

Putting it all together:

(5√19) x (6√2) = 30√38
