Step-by-step explanation:

(1/√4+√5)×(1/√4-√5)+(1/√5+√6)×(1/√5-√6)+(1/√6+√7)×(1/√6-√7)+(1/√7+√8)×(1/√7-√8)+(1/√8+2)

After rationalising denominators. ☝☝

1/(√4) ^2-(√5) ^2+1/(√5) ^2-(√6) ^2+1/(√6) ^2-(√7) ^2+1/(√7) ^2-(√8) ^2+1/(√8+2). {solving upper one.}

(1/4-5)+(1/5-6) +(1/6-7) +(1/7-8) +(1/√8+2).

(1/-1) +(1/-1) +(1/-1) +(1/-1) +√8-2.

-1-1-1-1+√8-2

√8-6 is the answer
