I'm not sure what you're asking. In simple text, you can do as you did in your original question, or something like 1100101_2 <-- notice, 2 is written in base 10. AF46_16 would be a base 16 number.

In programming, 0x prefix often indicates hexadecimal, 0 prefix indicates octal, and no prefix indicates decimal.

Is this a computerized test, or paper?

its just a practice paper.

If you're doing it on paper, just use a subscript with the base written in base 10.

Definitely WolframAlpha.
