Determine if the statements are true or not.

To do this, we convert DE from base 16 to base 10 using product rule.
So, we have:

In hexadecimal.

So, we have:


Hence:
(a) is true

First, convert D7 to base 10 using product rule


So, we have:


Next convert 215 to base 2, using division rule








Write the remainders from bottom to top.

<em>Hence (b) is false</em>

Convert 13 to base 10 using product rule


Hence; (c) is true
 
        
             
        
        
        
The beginning development of a
