In the above question it is given that,

The value is 105\times 95.

We have to evaluate the given equation by suitable identity.

The identity is comparing one form of equation with other form of equation.

Now, rewriting the equation we get,

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

Comparing with (a+b)(a-b)=a^{2}-b^{2}

Further substituting we get,

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

Hence we get the value as 9975.
