Answer:

Hey There!
The answer = 7 = ( Seventh Track of TS8= Seven )
Step-by-step explanation:

=>

3minutes 45 seconds = 3 45/60 = 3.75 minutes
28 copies/ 1 minute = x copies/3.75 minutes
using cross products
28 * 3.75 = 1 * x
105 = x
We can print 105 copies in 3 3/4 minutes
Answer:
.
For values of x>0, it can be rewritten as 
Step-by-step explanation:
For the expression:

We can apply this logarithmical property: 
Then,

If we assume values of <em>x </em>> 0 (non negative values for x), then the expression could be rewritten as follows:
, since 
We have to remember that <em>domain</em> (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:
Domain:
