Ta có:
425*27+425*72+425=425*(27+72+1)=425*100=42500
425x27+425x72+425
=425x27+425x72+425x1
=425x(27+72+1)
=425x100
=42500
425 x 27 + 425 x 72 + 425
= 425 x (27 + 72 + 1)
= 425 x 100
= 42500
= 425 . (27 + 72 + 1)
= 425 . 100
= 42500
Chúc bạn học tốt!
425 x 27 + 425 x 72 + 425
= 425 x (27 + 72 + 1)
= 425 x 100
= 42500
Học tốt!
