2009 2010 Power Multiply 2010 by |a-2010||+2011 by |b+1 in 2010|=0, and multiply the 2010 power of a by the 2009 power of b, 2009 2010 Power Multiply 2010 by |a-2010 2011 by |b+1 in 2010|=0, and multiply the 2010 power of a by the 2009 power of b,

2010×/A-2010/+2011×/b+1/2010/=0
Absolute value is not negative
So
A-2010=0
A =2010
B+1/2010=0
B=-1/2010
A^2010*b^2009=2010^2010*(-1/2010)^2009=-2010^2010*2010^(-2009)
=-2010

1+2-3-4+5+6-7-8+-7-8+...+2009+2011+2013

Is the last one wrong, it should be -2012. First you write the calculation

Original formula =(1+2-3-4)+(5+6-7-8)+...+(2009+2011-2012)+2012+2013. There is a total of 2012/4=503 brackets
=-4X503+2012+2013
=2013
