Answer 2

Answer:

The answer is  966000.

Step-by-step explanation:

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

We have to find the value of $983^{2} -17^{2}$

Substituting the values in our formula,

Here, a=983 and b=17

$983^{2} -17^{2}$ = (983+17)(983-17)

               = 1000 × 966

                = 966000
