Question:
Find the sum of the expression
A)7
B)8
C)9
D)10
Answer: A) 8
Explanation:
The Series can be re-written as (√2-√1)/(√2+√1)(√2-√1) + (√3-√2)/(√2+√2)(√3-√2) + .......... which simplifies to (√2-√1) + (√3-√2) + ..... (√81-√80) which again simplifies to √81 - √1 which is 8
Hence the Correct Option is A
