If `1/(sqrt(b)+sqrt(c)),1/(sqrt(c)+sqrt(a)),1/(sqrt(a)+sqrt(b))` are in `A.P.` , then `9^(ax+1),9^(bx+1),9^(cx+1),x !=0` are in

If (1)/(sqrt(b)+sqrt(c)),(1)/(sqrt(c)+sqrt(a)),(1)/(sqrt(a)+sqrt(b)) are in A.P.,then 9^(9x+1),9^(bx+1),9^(cx+1),x!=0 are in

If a,b,c are in A.P then (1)/(sqrt(b)-sqrt(c)),(1)/(sqrt(c)-sqrt(a)),(1)/(sqrt(a)-sqrt(b)) are in

a=9-4sqrt(5) , sqrt(a)-1/sqrt(a)=?

Show that 1/(sqrt10+sqrt13) , 1/(sqrt13+sqrt7) , 1/(sqrt7+sqrt10) are in A.P.

If a,b and c are in A.P then (1)/(sqrt(b)+sqrt(c)),(1)/(sqrt(c)+sqrt(a)),(1)/(sqrt(a)+sqrt(b)) are in

Let a, b, c be in AP. Consider the following statements: 1. (1)/(ab),(1)/(ca)" and "(1)/(bc)" are in AP." 2. (1)/(sqrt(b)+sqrt(c)),(1)/(sqrt(c)+sqrt(a))" and "(1)/(sqrt(a)+sqrt(b))" are in AP." Which of the statements given above is/are correct?

a=9-4sqrt(5),sqrt(a)-(1)/(sqrt(a))=?
