Step-by-step explanation:
The sum of two odd numbers is always even. So 3^11 + 5^13 is the sum of two odd numbers and is therefore even. Therefore, the smallest prime number dividing the sum 3¹¹ + 5¹³ is 2.

Any product of odd numbers is odd.
The sum of two odd numbers is even.
3^11 and 5^13 are both the product of odd numbers,
so they are both odd
So 3^11 + 5^13 is the sum of two odd numbers and
is therefore even.
Any even number is divisible by 2. Therefore 2 is the smallest prime
that divides 3^11 + 5^13. [In fact, 2 is the
smallest prime]
[ 3^11 + 5^13 = 1220880272 = 24*47*107*15173, but we don't need that!)
