\(B=\frac{2006\cdot125+1000}{126\cdot2005-880}\)
= \(\frac{2005\cdot125+125+1000}{2005\cdot126-880}=\frac{2005\cdot125+1125}{2005\cdot126-880}\)
=\(\frac{2005\cdot125+1125}{2005\cdot125+125-880}=1,007523912\)

\(\frac{2006\times125+100}{125\times200-880}=\frac{250850}{24120}\)

\(\frac{2010.125+1000}{126.2010-1010}=\frac{10\left(201.125+100\right)}{10\left(201.126-101\right)}=\frac{201.125-101+201}{2011.126-101}\)
\(=\frac{201.126-101}{201.126-101}=1\)
=2010 x 125 + 2010x 126 + 1000+1010
=2010 x 125 + 2010 x 126 + 2010
=2010 x ( 125 + 126 +1 )
=2010 x 252
=506520

\(\frac{2006\cdot125+1000}{126\cdot2005-888}=\frac{2005\cdot125+125+1000}{125\cdot2005+2005-888}=\frac{2005\cdot125+1125}{125\cdot2005+1117}\)
=> không tính nhanh được
\(\frac{2016x125+1000}{126x2015-880}\)
\(=\frac{2015x125+125+1000}{125x2015+2015-880}\)
\(=\frac{2015x125+1125}{125x2015+1135}=\frac{2015x125+1135-10}{125x2015+1135}\)
\(=1-\frac{10}{125x2015+1135}\)
bn cs chép nhầm đề ko z?
ai giải hộ mik vs :))
