Question

1.sa se calculeze: a) (-18 radical 6): (-9 radical 3 ) ori radical 2
2.sa se calculeze: a) ( radical 6+ radical 8 ) : radical 2
3.sa se calculeze: a) radical 3 ori (radical 2- radical 6)+ ( - radical 2 )de la 3

Answer 1

1. a) (-18√6): (-9√3 )×√2=2√2×√2=4
2.a) ( √6+ √8 ) : √2=( √6+ 2√2 ) : √2=√3+ 2
3.a) √3 × (√2- √6)+ ( - √2 )= √6-√18 - √2 =√6-3√2 - √2 =√6-4√2
