Show answer & explanation
Correct answer: B
To determine the number of bits required for a decimal number with 64 digits, multiply the digit count by log base 2 of 10 (approximately 3.3219). Calculation: 64 × 3.3219 ≈ 212.6. Since bits must be integers, round up to the nearest whole number, which is 213.
