Let x be a positive integer, what is the remainder when 3^(x+5)+4 is divided by 2? Choose the correct choice from the following choices
A) 4
B) 3
C) 2
D) 1
E) 0
For: (3^(x+5)+4)/2   Let n = x + 5   3^n   3^1 = 3   3^2 = 9   3^3 = 27   3^4 = 81   3^5 = 243, last digit pattern repeats 3, 9, 7, 1, 3, ....   Rule: x^(m+n) = (x^m)(x^n)   (3^(x))(3^5) =&gt; Now, (3)(3) + 3 = (9) + 3 =&gt; Finally, 12/2 and remainder is 0.   Answer: 0
