What is the representation of the hexadecimal number A63 in decimal form ?

To convert a hexadecimal number to a decimal number, we multiply each digit by 16 raised to the power of its position (starting from 0 on the right).

The hexadecimal number is A63. In the hexadecimal system, the letter 'A' represents the decimal value 10.

• Position 0 (rightmost): 3 × 16⁰ = 3 × 1 = 3
• Position 1: 6 × 16¹ = 6 × 16 = 96
• Position 2: A × 16² = 10 × 256 = 2560

Adding these values together: 2560 + 96 + 3 = 2659.

Thus, the decimal representation of the hexadecimal number A63 is 2659.
