Convert 57 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 >= 57

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 57

Since 256 is greater than 57, 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 57 is 3

Multiplying this coefficient by our original value, we get: 3 * 16 = 48

Add our new value to our running total, we get:
0 + 48 = 48

This is <= 57, so we assign our outside coefficient of 3 for this digit.

Our new sum becomes 48

Our hexadecimal notation is now equal to 3

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 57 is 9

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

Add our new value to our running total, we get:
48 + 9 = 57

This = 57, so we assign our outside coefficient of 9 for this digit.

Our new sum becomes 57

Our hexadecimal notation is now equal to 39
