Answer:
28 books
Step-by-step explanation:
Let x represent the number of books .William owned before anything happens
x/2 + 10 = 24
2(x/2 + 10) = 2(24)
x + 20 = 48
x = 48 - 20
x = 28
It is 3 is equivalent of y=2(x+3)^2+5
First, you'll use the "Log power rule," which says that

. In this case, you're going from the form on the right (with p in front of the log) to the form on the left (with p in the exponent position). So, the expression becomes:

Then, you'll use the "Log product rule," which says that

. Again, you're going from the form on the right to the form on the left (basically, from the sum of the logs, to a log of the products). So you get:

There's your expression simplified into a simple logarithm.
