Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 96000

(983)2−(17)2⇒(983+17)(983−17)⇒1000×966=966000∴9832−172 = 966000\begin{aligned} & (983)^2-(17)^2 \\ & \Rightarrow(983+17)(983-17) \\ & \Rightarrow 1000 \times 966=966000 \\ & \therefore 983^2-17^2 \text { = } 966000 \end{aligned}
