1.Rozwiaż układ rownan: 2x+3y=5 x+ 2y=2 2. Porównaj liczby: a) 2√3.....3√2 b)3,2×10⁻⁴.......1,2×10⁻³ c)(½)⁻⁵......(½)⁻²

a) 2x+3y=5 x+2y=2*(-2) 2x+3y=5 -2x-4y=-4 -y=-9/(-1) y=9 x+2y=2 x+18=2 x=-16

2x+3y=5 x+2y=2*(-2) 2x+3y=5 -2x-4y=-4 -y=-9/(-1) y=9 x+2y=2 x+18=2 x=-16

1) 2x+3y = 5 x+2y = 2 x = 2-2y 2(2-2y)+3y = 5 x = 2-2y 4-4y+3y = 5 x = 2-2y -y = 1 y = -1 x = 2-2×(-1) y = -1 x = 4 2) a) 2√3 < 3√2 √12 < √18 b)3,2×10⁻⁴ < 1,2×10⁻³ c)(½)⁻⁵ > (½)⁻² 2⁵ > 2² 32 > 4
