Answer 1

Answer:

a-1/a=6

or, (a-1/a)²=(6)²

or, a²-2+1/a²=36

or, a²+1/a²=36-2=34

Answer 2

Answer:

a-1/a = -6

or, a-1 = -6a

or, -1 = -6a-a

or, -1 = -7a

or, a = 1/7

then place this value in a*2+1 / a*2

= (1/7)*2+ 1/ (1/7)*2

= (1/49)+1 / (1/49)

= (50/49) / (1/49)

= 50/49 × (1/49)

= 50
