Answer 1

x+1^x=2
x+1=2
x=2-1;x=1

Answer 2

if x + 1/x = 2,.....(1)
To find
x.sq. + 1/x.sq.

from.. 1

x + 1/x = 2
...square both sides....
: . (x + 1/x).sq. = 2
: . x.sq. + 2x/x + (1/x).sq. = 4
: . x.sq. + 2 + (1/x)sq. = 4
: . x.sq. + 1/x.sq. = 4-2
: . x.sq. + 1/x.sq. = 2...

.here is your ans...
