Question

find the multiplication using identities :
95 × 105 ​

Answer 1

The given data in the above question,

It is given that the value is (105 x 95)

we have to evaluate the given equation we get.

Thus, evaluation of the given value we get,

Identities is the comparing of two expression we get,

Rewriting the given equation we get,

$(95\times 105)=(100-5)(100+5)$

Compare with identities we get,

$(a+b)(a-b)=a^{2}-b^{2}$

Substitute we get,

$\begin{aligned}95 \times 105 &=(100-5)(100+5) \\&=(100)^{2}-(5)^{2} \\&=10000-25 \\&=9975\end{aligned}$

Therefore we get the value as 9975.
