Question

EVALUATE 105*95 USING IDENTITIES

Answer 1

Answer:

we can write 105 100+ 5and 95 100-5 . A^ 2- B^ 2

Answer 2

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,

$109\times 95$

The identities are as follow,

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

Hence we get the value as 9975.
