Which of the following are valid hexadecimal numbers? How do you know?

ace f32e BABE BLEED 4567

Answer 1

ace f32e BABE 4567

Step-by-step explanation:

A hexadecimal number is a base 16 number and consists of digits [0,1,2,3,4,5,6,7,8,9] and characters [A,B,C,D,E,F].

ace is hexadecimal as it consists of characters a,c,e

f32e is hexadecimal as it consists of characters f,e and digits 3,2

BABE is hexadecimal as it consists of characters B,A,E.

BLEED is not hexadecimal as it contains character L which is invalid.

4567 is hexadecimal as it contains digits 4,5,6,7.
