Convert 164 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 >= 164

16⁰ = 1

16¹ = 16

16² = 256 <--- Stop: This is greater than 164

Since 256 is greater than 164, 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 164 is 10

Multiplying this coefficient by our original value, we get: 10 * 16 = 160

Add our new value to our running total, we get:
0 + 160 = 160

Hexadecimal (10 - 15) are represented by an (A-F) where 10 translates to the letter A

This is <= 164, so we assign our outside coefficient of A for this digit.

Our new sum becomes 160

Our hexadecimal notation is now equal to A

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 164 is 4

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

Add our new value to our running total, we get:
160 + 4 = 164

This = 164, so we assign our outside coefficient of 4 for this digit.

Our new sum becomes 164

Our hexadecimal notation is now equal to A4
