Răspuns

Explicație pas cu pas:

a)  2√3 × 3√2 = 6√6

b)  7√5 × ( - 3√2 ) = - 21√10

c)  17√5 × ( - 2√3 ) = - 34√15

d)   ( - 6√3 ) × ( - 2√3 ) = 12 √9 = 12 × 3 = 36

e)   - 4√2 × 3√2 = - 12√4 = - 12 × 2 = - 24

f)    7√6 × ( - 2√2 ) = - 14√12 = - 14 × 2√3 = - 28√3

g)   √6 × 2√5 × ( - 3√10 ) = - 6√300 = - 6 × 10√3 = - 60√3

h)   - √8 × √12 × ( - 4√20 ) × ( - 6√2 ) =

= - 2√3 × 2√3 × ( - 4 × 2√5 ) × ( - 6√2 ) =

= - 4 × 3 × ( - 8√5 ) × ( - 6√2) =

= + 96√5 × ( - 6√2 ) =

= - 576√10

i)   √51 × ( - 3√3 ) × ( - 4√17 ) × ( - 10√2 ) =

= ( √3 × √17 ) × 12 × ( √3 × √17 ) × ( - 10√2 ) =

= - 120 × 3 × 17 × √2 =

= - 6 120√2
