Answer 1

2)

a)  ( - 2√2 ) × ( 3√5 ) = - 6√10

b)   ( - 4√7 ) × ( - 3√7 ) = + 12√49 = 12 × 7 = 84

c)   2√6 × 3√2 = 6√12 = 6 × 2√3 = 12√3

d)   4√3 × ( - 8√15 ) = - 32√45 = - 32 × 3√5 = - 96√5

e)   0,5√7 × ( - 4√7 ) = - 2√49 = - 2 × 7 = - 14

f)    - 1,5√3 × 2√2 = - 3√6

g)     ( - 3 √6 / 4 ) ×  ( 2√3 / 3 ) = - √18 / 2 = - 3√2 / 2 = - 1,5√2

Answer 2

a) −6√10

b∫ 12×7=84

C)= 6√12 = 6×2√3 = 12√3

D) = −32√45 = − 32×3√5 = −96√5

e) = −2×7= −14

F)= −3√6

g) = −1/2√6 ×√3 = − 1/2√18 = − 1/2 × 3√2 = −3/2√2 = −1,5√2
