" 10."(sqrt(?)-1)^(2)=8-sqrt(28)

(sqrt(x)-1)^(2)=8-sqrt(28) find the value of x

(sqrt(2)+7)/(sqrt(2)-1)+sqrt(8)

Determine the value of (1)/(sqrt(1)+sqrt(2))+(1)/(sqrt(2)+sqrt(3))+(1)/(sqrt(3)+sqrt(4))+1+(1)/(sqrt(120)+sqrt(121)) (a) 8 (b) 10 (c) sqrt(120) (d) 12sqrt(2)

Simplify : (a+sqrt(a^(2)-1))^(8)-(a-sqrt(a^(2)-1))^(8)

Evaluate : (1)/(3-sqrt(8)) -(1)/(sqrt(8)-sqrt(7))+(1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)-2).

Let T = (1)/(3-sqrt(8))-(1)/(sqrt(8)-sqrt(7)) +(1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)+2) then-
