c. \( \sqrt{6} \times \sqrt{3} \)

Did you know that multiplying square roots can be done by simply multiplying the numbers inside? So, \( \sqrt{6} \times \sqrt{3} \) can be rewritten as \( \sqrt{6 \times 3} = \sqrt{18} \). And hold on—because \( \sqrt{18} \) can be simplified further into \( 3\sqrt{2} \)! In real-life terms, this concept comes in handy often, especially in fields like architecture or engineering where precise measurements are vital. For example, if you're calculating the area of a triangular garden and know the lengths of two sides, using square roots allows you to find the height efficiently, making it easier to determine how much soil you’ll need for planting!
