Question

So sánh 2 số 

a) \(2\sqrt{3}\)và \(3\sqrt{2}\)

b) \(6\sqrt{5}\)và \(5\sqrt{6}\)

Answer 1

a) \(2\sqrt{3}=\sqrt{4}.\sqrt{3}=\sqrt{12}< \sqrt{18}=\sqrt{9}.\sqrt{2}=3\sqrt{2}\)

b) \(6\sqrt{5}=\sqrt{36}.\sqrt{5}=\sqrt{36.5}=\sqrt{180}>\sqrt{150}=\sqrt{25}.\sqrt{6}=5\sqrt{6}\)

Answer 2

a) 2√3=√4.√3=√12<√18=√9.√2=3√2

b) 6√5=√36.√5=√36.5=√180>√150=√25.√6=5√6
