well 2 bits. I didnt know that was actually possible to calculate. Sounds like a networking problem? Maybe just the bits part throws me off.
I don't know, zegroes......it's just a variable.......and, since it's upper-case, we usually assume that it's different from the lower-case "b"......What is each suppposed to represent?????.......who knows????
There was nothing to "solve"......remember........we have to have an " = " sign in the problem to do that......I just "simplified" it using some basic rules involving exponents.....
