Answer 2

The value of $66\times 74$ is equal to 4884.

Step-by-step explanation:

We have,

$66\times 74$

To find, the value of $66\times 74 =?$

∴ $66\times 74$

$=(70-4)\times (70+4)$

Using the algebraic identity,

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

Here, a = 70 and b = 4

$=70^{2}-4^{2}$

$=4900-16$

= 4884

Hence,  the value of $66\times 74$ is equal to 4884.
