Số đấy là 32 nha p 

32=2^5

Ta có: |x| + |y| + |z|=0  =>x + y + z =0

=>x=0                 y=0                              z=0

k mik nha bạn@@@@@@@@@@@@@@

|x| + |y| + |z| = 0

Có |x| \(\ge\)0 với mọi x

|y| \(\ge\)0 với mọi y

|z| \(\ge\)0 với mọi z

=> Để |x| + |y| + |z| = 0 thì |x| = |y| = |z| = 0

=> x = y = z = 0

Last weekend I had a trip to Vung Tau with you in class I. It is an exciting and memorable trip. My trip lasted 3 days 4 nights. First, we see each other at 3. Then dinner together and then run straight out of Vung Tau to catch sunset. The weather today is beautiful cool and hard wind. I came out at 6 place, just at sunset. We go for a walk on the beach watching the sun set and picked up the shell and then writing letters on sand xò. Up to them to go to the hotel take the bathroom wash then the sea promenade and seafood drink several bottles of beer. However Sun was late at night so we about rooms early to have played much more tomorrow. In the morning we went swimming and then watch the sunrise. It was so awesome. Full of tired, we have breakfast and then take up the bath photo posted to facebook. We then split out the child about the child, the child, play kickball outings windsurfing. Our pm to go up the lighthouse and then through God's hands then take Jiang's coffee. Up about poker and then we slept so early tomorrow. Vung Tau is really sad farewell. I am very happy to have been visiting this place.

k mk nha!
