what if I assume that y=1 and vary x = 2,3,.... For all those options ST1 not sufficient as X can be odd or even. Please correct me.
Hi
ANGHOS82,
Notes:-
1) An odd number can be prime. (Example 1, 3,7,11 etc)
2) An even number can be prime. (Example only 2)
3)
1 is not prime.4) 1 is odd.
5) 1 raised to the power any positive integer is equal to 1.
As per your picked numbers,
y=1, x=2; so \(y^x=1^2=1\) , which is not a prime number, violating statement 1.
So, we can't pick y=1.
Hope it helps.
