Uyga vazifa: 285-misol va 286-masala.

285 Ko‘paytirishning guruhlash qonunidan foydala nib amallarni bajaring:

5⋅ 3⋅ 2⋅ 3=(5⋅ 2)⋅(3⋅ 3)=10 ⋅ 9=90 5⋅ 2⋅ 5⋅ 2

2⋅ 8⋅ 5 4⋅ 2⋅ 5⋅ 1 2⋅ 4⋅ 1⋅ 5 5⋅ 7⋅ 2

286 3 ta xonaning har birida bittadan qandil bor. Har bir qandilga 5 tadan lampochka qo‘yilgan. Agar qandillardagi 2 ta lampochka kuygan bo‘lsa, yaroqli lampochkalar nechta?
