我的方法是將答案還原成十進制再去比較題目的103(10)
A) 1100011(2) = 2^0*1 + 2^1*1 + 2^5*1 + 2^6*1 = 1 + 2 + 32 + 64 = 99(10)
B)1313(4) = 4^0*3 + 4^1*1 + 4^2*3 + 4^3*1 = 3 + 4 + 48 + 64 = 119(10)
C)77(8) = 8^0*7 + 8^1*7 = 7 + 56 = 63(10)
D)251(6) = 6^0*1 + 6^1*5 + 6^2*2 = 1 + 30 +72 = 103(10)
A) 1100011(2) = 2^0*1 + 2^1*1 + 2^5*1 + 2^6*1 = 1 + 2 + 32 + 64 = 99(10)
B)1313(4) = 4^0*3 + 4^1*1 + 4^2*3 + 4^3*1 = 3 + 4 + 48 + 64 = 119(10)
C)77(8) = 8^0*7 + 8^1*7 = 7 + 56 = 63(10)
D)251(6) = 6^0*1 + 6^1*5 + 6^2*2 = 1 + 30 +72 = 103(10)
