26m=26000mm
3.2m=3200mm
0.15m=150mm
3500dm=350000mm
4.8dm=480mm
0.05dm=5mm
3200cm=32000mm
15.5cm=155mm
1.2cm=12mm
ajutati-ma va rog
1.Amplificati raportul algebric x+√7/x-√7 cu x+√7
2.Simplificati raportul algebric pina la un raport ireductibil a^2-2ab+b^2/a^2-b^2
3.efectuati 5/x-2y - 3/x+2y
4.efectuati xy^2/x+y * (x+y)^2/xy
6.2-x/3x+12 : x^2-4/4x+x^2

Cand transformi din m in mm inmultesti cu 10^3
Cand transformi din dm in mm inmultesti cu 10^2
Cand transformi din cm in mm inmultesti cu 10
26 m=26000 mm
3,2 m=3,2*10^3=3200 mm
0,15 m=150 mm
350 dm=35000 mm
4,8 dm=480 mm
0,05 dm=5 mm
3200 cm=32000 mm
15,5 cm=155 mm
1,2 cm=12 mm
