Answer 1

b)
7*2^1997-6*2^1996-2*2^1998=
=2^1996(7*2^(1997-1996)-6*2^(1996-1996)-2*2^(1998-1998))=
=2^1996(7*2^1-6*2^0-2*2^2)=
=2^1996(7*2-6*1-2*4)=
=2^1996(14-6-8)=
=2^1996*0=
=0

Answer 2

7*2^1997-6*2^1996-2*2^1998=

=2^1996(7*2^(1997-1996)-6*2^(1996-1996)-2*2^(1998-1998))=

=2^1996(7*2^1-6*2^0-2*2^2)=

=2^1996(7*2-6*1-2*4)=

=2^1996(14-6-8)=

=2^1996*0=

=0
