nhé bạn
1001 x 9675,539 - 9675,539 =9675,539 x ( 1001-1) =9675,539 x 1000 =9675539
= 2012 x (1001-1) + 2013 x (999+1)
= 2012 x 1000 + 2013 x 1000
= 1000 x (2012+2013)
= 1000 x 4025 = 4025000
k mk nha
= 2012 x (1001-1) + 2013 x (999+1)
= 2012 x 1000 + 2013 x 1000
= 1000 x (2012+2013)
= 1000 x 4025 = 4025000
b)\(\left(2016.1017+2017.2018\right).\left(1+\frac{1}{2}:\frac{3}{2}-\frac{4}{3}\right)\)
\(\left(2016.2017+2017.2018\right)\left(1+\frac{1}{3}-\frac{4}{3}\right)\)
\(\left(2016.2017+2017.2018\right).\left(\frac{4}{3}-\frac{4}{3}\right)\)
\(\left(2016.2017+2017.2018\right).0\)
\(=0\)
. là x á nha
=\(\frac{2006}{2008}.\frac{2001}{2004}.\frac{2008}{2002}.\frac{2004}{2006}.\frac{1001}{2001}\)
=\(\frac{2006.2001.2008.2004.1001}{2008.2004.2002.2006.2001}\)
=\(\frac{1001}{2002}\)
= \(\frac{2006\cdot2001\cdot2008\cdot2004\cdot1001}{2008\cdot2004\cdot2002\cdot2006\cdot2001}\)
= \(\frac{1\cdot1\cdot1\cdot1\cdot1001}{1\cdot1\cdot2002\cdot1\cdot1}\)
= \(\frac{1}{2}\)
2017 x 1001 - 2017
=2017 x 1001 - 2017 x 1
=2017 x ( 1001 -1 )
=2017 x 1000
=2017000
={ 2017 - 2017} x 1001
=0 x 1001
=0
