A) -2+2 x [(-4) +(-6)]= B) -5-5 x [(-1)+2 x (-3)]= z obliczeniem proszę
A) -2+2 x [(-4) +(-6)]= -2 + 2 x (-10) = -2 + (-20) = -22
B) -5-5 x [(-1)+2 x (-3)]= -5 - 5 x [ (-1) + (-6) ] = -5 - 5 x (-7) = - 5 - (-35) = -5 + 35 = 30
A) -2 + 2x[(-4) + (-6)] = -2 + 2x[ -4 - 6 ] = -2 + 2x * (-10) = -2 - 20x
B) -5 - 5x[(-1) + 2x(-3)] = -5 - 5x[ -1 - 6x] = -5 + 5x + 30x = -5 + 35x
