Multiple choice Choose the biggest number: √6, 2√3, √15, 3√2 √6 2√3 √15 3√2 Reveal answer Fill a bubble to check yourself D Correct answer Explanation Convert all to square roots: sqrt(6) is sqrt(6), 2*sqrt(3) = sqrt(4 * 3) = sqrt(12), sqrt(15) is sqrt(15), and 3*sqrt(2) = sqrt(9 * 2) = sqrt(18). Since 18 is the largest, 3*sqrt(2) is the biggest.
