cac bạn nhớ làm giup minh voi mai minh kiem tra mon toan roi
giup wm giai bai toan nay
cho: -1\2=y-2\3=z-3\4 va 2x+y-z=50
tim x,y,z
Giup mik bai nay nha : |x|=(-1/2)^2-1^2011+2/4×(-1/2)+√25/16
\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+....+\frac{1}{2011}}{\frac{2010}{1}+\frac{2009}{2}+\frac{2008}{3}+....+\frac{1}{2010}}\)
Cac ban giai giup minh voi minh minh kiem tr roi
giai co loi giai nha

(giup mik voi mik can loi giai chi tiet
cam on may thanh da giup mik)
Ban nao bt giup mk nha hua se tick
