Question

If a= 6 - √35,find the value of a²+1/a² please answer it properly

Answer 1

Answer:

HERE IS UR ANSWER

Step-by-step explanation:

a=6-_/35

1/a=1/(6-_/35)=(6+_/35)(6^2-35)=6+_/35 (rationalised the denominator)

So, a^2+1/a^2=(6-_/35)^2(6+_/35)^2

=36+35-12_/35 +36+35+12_/35

=71+71=142...

Answer 2

Step-by-step explanation:

a^2+1/a

So, put the value of a

=(6-(√35))^2+1/(6-(√35))^2

=(36-35)+1/(36-35

=1+1/1

=2/1

=2
