- A.0
- B.1/2
- C.1
- D.10
Show the answer and explanation
Answer: C (1)
Explanation
√(x2n−3) = xn−3/2, so the denominator is x2n+5/2+n−3/2 = x3n+1. The fraction equals 1.
Simplify x3n+1/(x2n+5/2√(x2n−3))
Answer: C (1)
√(x2n−3) = xn−3/2, so the denominator is x2n+5/2+n−3/2 = x3n+1. The fraction equals 1.
