✔ 最佳答案
5 = 1x2^2 + 1x2^00.13 = 1x2^(-3) + 1x2^(-8) + 1x2^(-10) + ...
所以 5.13 = 101.0010000101... (binary)
25 = 1x16^1 + 9x16^0
0.17 = 2x16^(-1) + 11x16^(-2) + 8x16^(-3) + 5x16^(-4) + 1x16^(-5) + ...
所以 25.17 = 19.2B851... (hexadecimal)

5 = 1 x 2^2 + 0 x 2^1 + 1 x 2^0 = 101(binary)
13 = 1 x 2^3 + 1 x 2^2 + 0 x 2^1 + 1 x 2^0 = 1101(binary)
25 = 1 x 16^1 + 9 x 16^0 = 19(hexadecimal)
17 = 1 x 16^1 + 1 x 16^0 = 11(hexadecimal)
13 = 1 x 2^3 + 1 x 2^2 + 0 x 2^1 + 1 x 2^0 = 1101(binary)
25 = 1 x 16^1 + 9 x 16^0 = 19(hexadecimal)
17 = 1 x 16^1 + 1 x 16^0 = 11(hexadecimal)
