Convert 84 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 >= 84

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 84

Since 256 is greater than 84, 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 84 is 5

Multiplying this coefficient by our original value, we get: 5 * 16 = 80

Add our new value to our running total, we get:
0 + 80 = 80

This is <= 84, so we assign our outside coefficient of 5 for this digit.

Our new sum becomes 80

Our hexadecimal notation is now equal to 5

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 84 is 4

Multiplying this coefficient by our original value, we get: 4 * 1 = 4

Add our new value to our running total, we get:
80 + 4 = 84

This = 84, so we assign our outside coefficient of 4 for this digit.

Our new sum becomes 84

Our hexadecimal notation is now equal to 54
