Evaluate using suitable identity:
e). 102 × 98

Step-by-step explanation:
[tex]\sf \longmapsto 102 \times 98[/tex]
[tex]\sf \longmapsto (a + b)(a - b) = a^2 - b^2[/tex]
Here,
[tex]\sf \longmapsto (100 + 2)(100 - 2) = 100^2 - 2^2[/tex]
[tex]\sf \longmapsto 100^2 - 2^2[/tex]
[tex]\sf \longmapsto 10000 - 4[/tex]
[tex]\sf \longmapsto 9996[/tex]
Answer:
9996
Step-by-step explanation:
Algebraic Identity: (a-b)(a+b)=a²-b²
102×98=(100+2)(100-2)
=100²-2²
=10000-4
=9996
