Answer 1

In a binary number, the digits from the right are equal to powers of two. The first digit from the right is equal to the zeroth power of two, the second digit from the right is equal to the first power of two, and so on.

Step-by-step explanation:

In a binary number, the digits from the right are equal to the powers of two. The first digit from the right is equal to the zeroth power of two, the second digit from the right is equal to the first power of two, and so on.

For example, in the binary number 1011, the rightmost digit is 1, which is equal to 20 = 1. The second digit from the right is also 1, which is equal to 21 = 2. The third digit from the right is 0, so it represents 22 = 4. The fourth digit from the right is 1, so it represents 23 = 8.
