Short Answer

Expert verified

Part (a) $5 \sqrt{2}$

Part (b) $90 \sqrt{2}$

Step by step solution

Part (a) Step 1. Given information.

The given expression is:

$\sqrt{5} \cdot \sqrt{10}$

Part (a) Step 2. Simplify the expression.

$\sqrt{5} \cdot \sqrt{10}$

Multiply using the product property,

$\sqrt{50}$
