Answer 2

Answer:

5

Step-by-step explanation:

We have,

(1/3 - √8) - (1/√8 - √7) + (1/√7 - √6) - (1/√6 - √5) + (1/√5 - 2)

We have to rationalize, we will get

=> [(1/3 - √8) * (3 + √8)/(3 + √8)] - [(1/√8 - √7) * (√8 + √7)/(√8 + √7)] + [(1/√7 - √6) * (√7 + √6)/(√7 + √6)] - [(1/√6 - √5) * (6 + √5/√6 + √5)] + [(1/√5 - 2) * (√5 + 2)/(√5 + 2)]

=> [(3+√8)/9-8]-[(√8+√7)/8-7]+[(√7+√6)/7-6]-[(√6+√5)/6-5]+[(√5+2)/5-2]

=> 3+√8-√8-√7+√7+√6-√6-√5+√5+2

=> 3 + 2

=> 5
