Moderate -0.8 This is a straightforward base conversion problem requiring repeated division by 16 and tracking remainders. While it involves multiple steps (5 divisions for a 5-digit number), the algorithm is mechanical and requires no problem-solving insight—just careful arithmetic and knowledge of hexadecimal notation (A-F for 10-15). Easier than average A-level questions which typically require more conceptual understanding.
1 In this question you must show detailed reasoning.
Express the number $\mathbf { 4 1 7 2 3 } _ { 10 }$ in hexadecimal (base 16).
