{[(169:13-2la puterea 3) : 5+(7 x 2 la puterea 3 -2 x 3) :5+2 la puterea 3] : 19+5} x2 la puterea 3 - 2 la puterea 4 x3

Answer 1

Răspuns:

{[(169:13-2³) :5+(7×2³-2×3):5+2³]:19+5}×2³-2⁴×3=

={[(13-8):5+(7×8-6):5+8]:19+5}×8-16×3=

=[(5:5+50:5+8):19+5]×8-48=

=[(1+10+8):19]×8-48=

=(19:19)×8-48=

=1×8-48=

=8-48=

=-40
