Convert 73 from decimal to hexadecimal

(base 16) notation:

Power Test

Raise our base of 16 to a power

Start at 0 and increasing by 1 until it is >= 73

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 73

Since 256 is greater than 73, we use 1 power less as our starting point which equals 1

Build hexadecimal notation

Work backwards from a power of 1

We start with a total sum of 0:

16¹ = 16

The highest coefficient less than 15 we can multiply this by to stay under 73 is 4

Multiplying this coefficient by our original value, we get: 4 * 16 = 64

Add our new value to our running total, we get:
0 + 64 = 64

This is <= 73, so we assign our outside coefficient of 4 for this digit.

Our new sum becomes 64

Our hexadecimal notation is now equal to 4

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 73 is 9

Multiplying this coefficient by our original value, we get: 9 * 1 = 9

Add our new value to our running total, we get:
64 + 9 = 73

This = 73, so we assign our outside coefficient of 9 for this digit.

Our new sum becomes 73

Our hexadecimal notation is now equal to 49
