How many select lines does a 5-input multiplexer have?
I'm confused since usually the number of inputs is 2^n and n is the number of select lines. But 5 doesn't work for that.

A 5-input multiplexer would just be an 8-input multiplexer where you didn't use three of the inputs. Multiplexers are always built with 2^n inputs.

It has 3 lines.
1 line selects 0 or 1 (2)
2 lines selects 0 to 3 (4)
3 lines selects 0 to 7 (8)
