Root2xroot8=4
root5/root20=0,5
root18xroot2:6=1
root30xroot50/root15=1500

√2 * √8 = √16 = 4
√5/√20 = √5:20 = √0,25 = 0,5
√18 * √2 : 6 = √36 :6 = 6:6 = 1
√30 * √50/√15 = √30 * √50:15 = √30 * √10:3 = √30*3⅓ = √100 = 10

Oblicz;
root2 x root8=root16=4
root5/root20=root5/20=root1/4=1/2
root18 x root2 : 6=root18*2:6=1
root30 x root50/root15= root30*root10/3=root30*10/3=root100=10
