Question

what is binary number for 11​

Answer 1

Answer:

1011

Explanation:

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

...

Now, to get 11 try to some up these numbers to get 11 . When we use,

1+ 2+ 8 = 11

i.e. 2^3 + 2^1 + 2^0.

When we use 2^n for adding we put there 1 and when a certain power(2^n) is not used we replace it with 0

1 0 1 1

➖ ➖ ➖ ➖

2^3 2^2 2^1 2^0
