Hexadecimal is a numbering system commonly used in computer science and digital systems. It is base 16, meaning it utilizes 16 symbols to represent numbers. These symbols are 0-9 for values 0-9 and A-F for values 10-15. Each digit in a hexadecimal number represents a power of 16. Now let’s decode the hexadecimal value of 238F.
The given value, 238F, can be broken down into its individual digits: 2, 3, 8, and F. We need to assign a decimal value to each of these hexadecimal digits. For the digits 0-9, the decimal and hexadecimal values remain the same. However, since F corresponds to 15, we assign a decimal value of 15 for F.
Therefore, we can convert these hexadecimal digits into decimal values: 2 (decimal value = 2), 3 (decimal value = 3), 8 (decimal value = 8), and F (decimal value = 15). Now, we multiply each digit with its appropriate power of 16. The rightmost digit corresponds to 16^0, the second rightmost digit corresponds to 16^1, and so on.
Multiplying the decimal values of each digit with their corresponding power of 16:
2 * 16^3 + 3 * 16^2 + 8 * 16^1 + F * 16^0.
Simplifying this expression, we get:
2 * 4096 + 3 * 256 + 8 * 16 + 15 * 1.
Calculating the values, we have:
8192 + 768 + 128 + 15.
Finally, combining these values, we arrive at the decimal equivalent of the hexadecimal value 238F:
**8,103**.
