BCNN( 10; 16; 7) = 560
cl: \(10=2\cdot5\)
\(16=2^4\)
\(7=7\cdot1\)
=> BCNN( 10; 16; 7) = \(2^4\cdot5\cdot7\cdot1=560\)

1. (A+B)2 = A2+2AB+B2
2. (A – B)2= A2 – 2AB+ B2
3. A2 – B2= (A-B)(A+B)
4. (A+B)3= A3+3A2B +3AB2+B3
5. (A – B)3 = A3- 3A2B+ 3AB2- B3
6. A3 + B3= (A+B)(A2- AB +B2)
7. A3- B3= (A- B)(A2+ AB+ B2)
8. (A+B+C)2= A2+ B2+C2+2 AB+ 2AC+ 2BC
* CHÚ Ý;
a/ a+b= -(-a-b) ; b/ (a+b)2= (-a-b)2 ; c/ (a-b)2= (b-a)2 ; d/ (a+b)3= -(-a-b)3 e/ (a-b)3=-(-a+b)3

(a+b)^2=a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2
a^2-b^2=(a+b)(a-b)
(a+b)^3=a^3+3a^2b+3ab^2+b^3
(a-b)^3=a^3-3a^2b+3ab^2-b^3
a^3+b^3=(a+b)(a^2-ab+b^2)
a^3-b^3=(a-b)(a^2+ab+b^2)

John’s daily routine is a little boring, but he s it. He usually gets up at about 6:00 or 6:30 in the morning after his alarm wakes him up. First, he brushes his teeth and shaves and washes his face. Then he gets dressed and goes downstairs to have breakfast with his family. He always has juice, cereal, and lots of fruit. He takes a bus to work because he doesn’t to drive, and he always arrives at his office before 8:00. Five o’clock is his favorite time of the day because he finishes work and hurries back home to see his wife and children again. He has two boys, Tomas, who is 6 years old and Patrick, who is 8. They eat dinner together in their dining room at around 6:00, and after that he spends time with his wife and kids at home. They really enjoy watching their favorite shows together. In addition, two or three times a week he does exercise in the evening, so he can stay strong and healthy. He thinks that this is very important. Finally at about 9:30, he goes to bed, reads for a while, and then falls asleep. Sure, some people think that his routine is a little boring, but on weekends he loves to fly airplanes for fun! It’s his favorite hobby.
