Question

solve by using identities 103 X 97 . ​

Answer 1

Answer:

103×97=(100+3)(100−3)

Using, a  2 −b  2

=(a+b)(a−b)

=(100)  2  −(3)  2

 

=10000−9

=9991

Step-by-step explanation:

Answer 2

Answer:

Q) 103 X 97

= (100 + 3) (100 - 3)

= (a + b) (a - b)

= $a^{2} - b^{2}$

= $100^{2} - 3^{2}$

= 10000 - 9

= 9991
