If x+1/X is equal to 5 then w hat is x5+/x5

• x+1/x=5 ----- 1.
  (x)^5 + (1/x)^5 = ?
  
  Squaring both sides in 1.
  (x)^2 + (1/x)^2 = 23 ----2.
  
  Again, Cubing both sides in 1.
  (X)^3 + (1/x)^3 = 110 -----3.
  
  Now, Multiply 2 and 3
  (x)^5 + (x+1/x) + (1/x)^5 = 2530
  (x)^5 + (1/x)^5 = 2525 (on taking value from 1.)
