Answer 1

Answer:

103×107

=11021

104×96

=9984

Answer 2

Answer:

(I) 103x 107 Note :

(x-y) (x+y) = X2 - y2 ( x2;y2 means x sq. and y sq.)

(105-2) (105+2)= 105 sq. - 2 sq.

11025-4

= 11021

(ii) 104x 96 Note :

(x+y) (x-y) = X2 - y2 ( x2;y2 means x sq. and y sq.)

(100+4) (100-4) = 100 sq. - 4 sq.

10000- 16

= 9984
