e) 1946 x 131 + 1000 / 132 x 1946 - 946
1946 x 131 + 1000 / (131+1) x 1946 - 946
1946 x 131 + 1000 / 131 x 1946 + 1946 -946
1946 x 131 + 1000 / 131 x 1946 + 1000 = 1
t i c k nha
1946 x 131 + 1000 / (131+1) x 1946 - 946
1946 x 131 + 1000 / 131 x 1946 + 1946 -946
1946 x 131 + 1000 / 131 x 1946 + (1946 - 946)
1946 x 131 + 1000 / 131 x 1946 + 1000 = 1
tick cho mik nha
Cách 2:
Xét theo tử số, ta có:
1946 x 131 +1000
=>1946 x (132 - 1) + 1000
<=>1946 x 132 - 1946 +1000
=> 1946 x 132 - 946
Vậy: =1
1946 x 131 + 1000 / 1946 x 132 - 946
Tinh nhanh
\(\frac{1946\times131+1000}{1946\times132-946}\)
\(=\frac{1946\times131+1000}{1946\times\left(131+1\right)-946}\)
\(=\frac{1946\times131+1000}{1946\times131+1946-946}\)
\(=\frac{1946\times131+1000}{1946\times131+1000}\)

câu đầu bằng=2561526
còn lại là=255926
k mình nhé
câu 1 =2561526
câu 2 =255926
đúng thì k cho mình nha
1946 x 131 + 1000 \ 132 x 1946 - 946
2018 x 215 -918 \ 2018 x 214 + 1100
a) 1946 x 131 + 1000 : 132 x 1946 - 946
= 1946 x ( 131 + 1000 : 132 ) - 946
= 1946 x ( 131 + 7,57 ) - 946
= 1946 x 138,57 - 946
= 268 711,22
Bạn Trần Nhật Dương ơi trên là phân số đó ko phải số tự nhiên đâu
Đấy là mình làm luôn , 1000/132 mình tách thành 1000:132
Mình cần gấp trong hôm nay ai biet chỉ mình nha
