Question

Scoateti factorii de sub radical:
V50; V8; V20; V27; V12​

Answer 1

$\sqrt{50} =\sqrt{2*5^2} =5\sqrt{2} \\\sqrt{8} =\sqrt{2^3}=\sqrt{2^2*2}=2\sqrt{2} \\\sqrt{20} =\sqrt{2^2*5} =2\sqrt{5} \\\sqrt{27} =\sqrt{3^3} =\sqrt{3^2*3} =3\sqrt{3} \\\sqrt{12} =\sqrt{2^2*3} =2\sqrt{3}$

Answer 2

√50=√(5²×2)=5√2

√8=√(2²×2)=2√2

√20=√(2²×5)=2√5

√27=√(3²×3)=3√3

√12=√(2²×3)=2√3
