Answer:
The answer is "
"
Explanation:
The Combinations could be produced by using n-bits 
. It s enables you to generate the 4-bit numbers that are:
combinations.
for the 4-bit, the combination of 2 = 16, which are its possible combination and for the 10 variations appropriate 16 combinations are used, As we know for 4 bit 16 Combinations can be generated which are from 0 to 15.
Explanation:
Age = 23.
To convert a base 10 number to hexadecimal number we have to repeatedly divide the decimal number by 16 until it becomes zero and store the remainder in the reverse direction of obtaining them.
23/16=1 remainder = 5
1/16=0 remainder = 1
Now writing the remainders in reverse direction that is 15.
My age in hexadecimal number is (15)₁₆.
