1. Unsigned Integers If we have an -digit unsigned numeral da-Idn-2...do in radix (or base) r, then the value of that numeral is i, which is basically aying that instead of a 10's or 100's place we have an 's or place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down large number we typically use the IEC prefixing system Ki 210, Mi -220, Gi -230, Ti 240, Pi- 250, Ei 2, Zi 2, Yi-280 1.1 Conversions a. Convert the following from their initial radix to the other two common radices: 0b10001110, 0xC3BA, 81, 0b100100100, 0xBCA1, 0, 42, 0xBAC4 b. Write the following using IEC prefixes: 214, 243,23, 258, 264, 242 c. Write the following as powers of 2: 2 Ki, 512 Pi, 256 Ki, 32 Gi, 64 Mi, 8 Ei
