Q: [(3.537 - .948) 2 + (3.537 + .948) 2] / [(3.537) 2 + (.948) 2] =?

Given expression = [(3.537 - .948)2 + (3.537 + .948)2] / [(3.537)2 + (.948)2] = [(a - b)2 + (a + b)2] / (a2 + b2) (Where a = 3.537 and b = 0.948) = 2(a2 +b2) / (a2 +b2) = 2

4.485
2.589
4
2

Correct Answer: 2

Explanation:

Given expression = [(3.537 - .948)² + (3.537 + .948)²] / [(3.537)² + (.948)²]
= [(a - b)² + (a + b)²] / (a² + b²)
(Where a = 3.537 and b = 0.948)
= 2(a² +b²) / (a² +b²)
= 2
