प्रश्न

What is the conjugate of `(sqrt(5 + 12i) + sqrt(5 - 12i))/(sqrt(5 + 12i) - sqrt(5 - 12i))`?

योग

उत्तर

Let z = `(sqrt(5 + 12i) + sqrt(5 - 12i))/(sqrt(5 + 12i) - sqrt(5 - 12i)) xx (sqrt(5 + 12i) + sqrt(5 - 12i))/(sqrt(5 + 12i) + sqrt(5 - 12i))`

= `(5 + 12i + 5 - 12i + 2 sqrt(25 + 144))/(5 + 12i - 5 + 12i)`

= `3/(2i)`

= `(3i)/(-2)`

= `0 - 3/2 i`

Therefore, the conjugate of z = `0 + 3/2 i`.
