निम्नलिखित व्यंजक को सरल कीजिए: ((525 + 175)^2 – (525 – 175)^2) / (525 * 175)

Question Figure

Options:

  • a) 700
  • b) 4
  • c) 2
  • d) 350
  • a) 700
  • b) 4
  • c) 2
  • d) 350

correct answer : b)

Explanation:

Let a = 525 and b = 175. The expression is in the form: ((a + b)^2 – (a – b)^2) / (a * b). Since (a + b)^2 – (a – b)^2 = 4ab, the expression simplifies to 4ab / ab = 4.

मान लीजिए a = 525 और b = 175। व्यंजक का रूप इस प्रकार है: ((a + b)² – (a – b)²) / (a * b)। चूँकि (a + b)² – (a – b)² = 4ab होता है, इसलिए व्यंजक सरल होकर 4ab / ab = 4 हो जाता है।
