What is the decimal equivalent of the binary number 1010?

To convert the binary number 1010 to its decimal equivalent, we need to understand how the binary number system works. In binary, each digit represents a power of 2, starting from the rightmost digit, which represents 2^0 (or 1).

For the binary number 1010:

• The rightmost digit (0) represents 2^0, which equals 0.

• The next digit (1) represents 2^1, which equals 2.

• The next digit (0) represents 2^2, which equals 0.

• The leftmost digit (1) represents 2^3, which equals 8.

Now, we add the values from the positions where there are 1s:

• 0 (from the first digit) +

• 2 (from the second digit) +

• 0 (from the third digit) +

• 8 (from the fourth digit) = 0 + 2 + 0 + 8 = 10.

Thus, the decimal equivalent of the binary number 1010 is 10, making the correct answer the representation of the decimal number in the provided choices.
