Answer 2

GivEn:

• Using identity for difference of two squares, find the value of 101 x 99.

To FiNd:

• Value of 101 × 99 with suitable identity for the difference of two squares.

IdentiTy UsEd:

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

SoluTion:

We are been used to find the value of $\sf{101 \times 99}$ with our identity.

Solving with our Suitable identify:

$\\ \\ \longrightarrow{101 \times 99} \\ \\ \longrightarrow{(100 + 1)(100 - 1)} \\ \\ \longrightarrow{{(100)}^{2} - ( {1)} }^{2} \\ \\ \longrightarrow{10000 - 1} \\ \\ \longrightarrow{9999}$

Thus,

$\therefore$ The value of 101 × 99 using the suitable identity is 9999.
