Convert 297 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 >= 297

16⁰ = 1

16¹ = 16

16² = 256

16³ = 4096 <--- Stop: This is greater than 297

Since 4096 is greater than 297, we use 1 power less as our starting point which equals 2

Build hexadecimal notation

Work backwards from a power of 2

We start with a total sum of 0:

16² = 256

The highest coefficient less than 15 we can multiply this by to stay under 297 is 1

Multiplying this coefficient by our original value, we get: 1 * 256 = 256

Add our new value to our running total, we get:
0 + 256 = 256

This is <= 297, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 256

Our hexadecimal notation is now equal to 1

16¹ = 16

The highest coefficient less than 15 we can multiply this by to stay under 297 is 2

Multiplying this coefficient by our original value, we get: 2 * 16 = 32

Add our new value to our running total, we get:
256 + 32 = 288

This is <= 297, so we assign our outside coefficient of 2 for this digit.

Our new sum becomes 288

Our hexadecimal notation is now equal to 12

16⁰ = 1

The highest coefficient less than 15 we can multiply this by to stay under 297 is 9

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

Add our new value to our running total, we get:
288 + 9 = 297

This = 297, so we assign our outside coefficient of 9 for this digit.

Our new sum becomes 297

Our hexadecimal notation is now equal to 129
