tính nhanh nhé
Tính nhanh: (-67).(1 – 301 ) – 301. 67
(-67).(1 – 301 ) – 301. 67 = (-67).1 + 67.301 – 67. 301 = -67

Ai đúng mik sẽ tick nha
-67.(1 - 301) - 301.67
= -67.(-300) - 301.67
= 67.300 - 301.67
= 67(300 - 301)
= 67.(-1)
= -67
\(\left(-67\right)\left(1-301\right)-301\cdot67\)
\(=\left(-67\right)\left(-300\right)-301\cdot67\)
\(=67\cdot300-301\cdot67\)
\(=67\left(300-301\right)\)
\(=67\cdot\left(-1\right)\)
