Question

4 Rezolvați, efectuând calculele cât mai convenabil: a (-2)×15×(-50) = b (+4)×(-8)×(-25) = c (+20)×(-3)×5 = d (-50)× 14×(-2) = e (-6)×(-4) ×(-8)×(-25) = f (+5) ×(-3)×(-4) ×(-20) = ​

Answer 1

Răspuns:

Explicație pas cu pas:

a) (-2)×15×(-50) = -30x(-50)=1500

b) (+4)×(-8)×(-25) = -32x(-25)=800

c) (+20)×(-3)×5 = -60x5=-300

d) (-50)× 14×(-2) = -700x(-2)=1400

e) (-6)×(-4) ×(-8)×(-25) = 24x200=4800

f) (+5) ×(-3)×(-4) ×(-20) = ​-15x80=-1200

Succes!
