सविस्तर स्पष्टीकरण (Detailed Explanation):
अचूक उत्तर: पर्याय (1)
Given:
\(\dfrac{(3.49)^2-(0.51)^2}{(3.49-0.51)}\) = ?
Formula used:
\(\dfrac{a^2-b^2}{a-b} = [(a+b)(a-b)]/(a-b) = (a+b)\)
Calculation:
\(\dfrac{(3.49)^2-(0.51)^2}{(3.49-0.51)}\) = ?
⇒ \(\dfrac{a^2-b^2}{a-b} = a+b\)
⇒ ? = 3.49 + 0.51
⇒ ? = 4
∴ The correct answer is option (1).
