In fact there is a much faster way to solve this question:
2^1 = 10 base 2
2^2 = 100
2^3 = 1000
2^4 = 10000
. . .
2^13 = 10000000000000
therefore
2^13+2^4+3 =
10000000000000
+ 10000
+ 11 (which is 3 base 10)
= 10000000010011
2^1 = 10 base 2
2^2 = 100
2^3 = 1000
2^4 = 10000
. . .
2^13 = 10000000000000
therefore
2^13+2^4+3 =
10000000000000
+ 10000
+ 11 (which is 3 base 10)
= 10000000010011
