Due to basic error in not using brackets, question may be read in a number of different ways.
Will try:-
( 2^(100) + 2^95 ) / ( 2^100 - 2^95 )
[ 2^(95) (2^5 + 1) ] / [ 2^95(2^5 - 1) ]
( 2^5 + 1 ) / ( 2^5 - 1 )
33 / 31
PS
Remember brackets for next year and thereafter!
Good luck.

Its not tough.
2^100 + 2^95 / 2^100 - 2^95
=2^95(2^5+1)/2^95(2^5-1)
Here, 2^95 cancels out from Numerator and Denominator
2^5=32
So, it becomes
32+1/32-1
=33/31
I told you its easy. Don't get afraid when you see such numbers. When numbers are big, there will be an easy way. Its so simple. Giving Best Answer is always welcomed and thank you.

2^100 + 2^95 / 2^100- 2^95 = 2^95(2^5+1) / 2^95(2^5-1)
=(32+1) / (32-1) = 33/31
[ use 2^100= 2^95 x 2^5]

(2^100 + 2^95)/(2^100-2^95) =
2^95(2^5 + 1)/2^95(2^5 - 1) = (2^5 +1)/(2^5 - 1) =
(32 + 1)/(32 - 1) = 33/31
~~~

2^95(2^5+1) / (2^95(2^5-1)
= (2^5+1)/(2^5-1)
= 33/31

assume dat the value is x
then apply componendo dividendo
then you will get the answer on simplifying
