Step-by-step explanation:
The question should be like this ,
10.5 × 9.5 Evaluate using identity.
Now,
10.5 × 9.5
= (10+0.5)(10-0.5)
= (10)²- (0.5)²
/* By an algebraic identity:
(a+b)(a-b)=a square - b square
= 100 - 0.25
= 99.75
Therefore,.
10.5 × 9.5 = 99.75

Answer:
105×95
(100+5)(100-5)
identity used : (a+b)(a-b) = a^2-b^2
=>(100+5)(100-5) = (100)^2-(5)^2
= 10000-25
= 9975
hope it works ❤️❤️。◕‿◕。
