Question

2002*2002*(1/2000*2001+1/2001*2002)

Answer 1

2002*2002*(1/2000*2001+1/2001*2002)

=(2002*2002)/(2000*2001)+(2002*2002)/(2001*2002)

=(2002*2002)/(2000*2001)+(2002/2001)

=(2002/2000)(2002/2001)+(2002/2001)

=(2002/2000+1)*(2002/2001)

=(1001/1000+1)*(2002/2001)

=(2001/1000)*(2002/2001)

=2002/1000

=2.002
