1. A, B>0, is a^b greater than 10,000?
1. a+b =20
2. b^a>10,000
OA is E
if you put in values it could be the easier but at the same time eyeballing values is risky...is there another way?
2. Is x^y>1?
1. x>1
2. y<1
OA is E
is there a quicker way to solve these ds problems?

For the second problem:
2. Is x^y>1?
1. x>1
2. y<1
OA is E
Not sure why this is E. I thought it would be B.
Since Y is less than 1. It can either be
0.....in which case no matter what X is, the result would equal one.
less than 0......in which case no matter what X is, result would be a fraction.
Both results are less than 1. This would answer the problem as in "No"
I'm sure I'm missing something here...

Ques 1
a>0, b>0 a^b >10000 ???
Statement I
a+b=20
a=10, b=10 a^b >10000
a = 1, b =19 a^b <10000
Therefore Insufficient.
Statement II
b^a>10,000
b=10, a=10 a^b>10000
b=100000, a=1 a^b<10000
Therefore insufficient.
Combining I and II
a+b =20
b^a>10000
a=10, b=10 a^b>10000
a=18,b=2, 2^18>10000 but 18^2<10000
Therefore Insufficient.
Hence E is the answer.
Ques 2
