Question

Măcar câteva exerciții să le rezolve cineva.
Vă rog!:))))

Answer 1

16. a) radical 3× (radical 2 - radical 3)= radical 3 ×radical 2 - radical 3× radical 3= radical 6-3

2 radical 3× (radical 3+ radical 27) = 2 radical 3× (radical 3 + 3 radical 3) = 2radical 3× 4radical 3= 2×3×4 =24

3 radical 8 ×(radical 2- radical 32)= 3 radical 8 ×(-3 radical 2) = -3 × 2radical 2× 3 radical 2 =-3×2×2×3= -36

-2 radical 5×(radical 125- radical 45)= -2 radical 5×( 5radical 5-3radical 5)= -2 radical 5 × 2radical 5= -2×5×2= -20
