Answer:
Answer: 1/81
First you simplify it to 3^-4
Then express it with a positive exponent
which goes to 1/3^4
Then evaluate it to 1/81
(2√5 + 3(√7))^2
(2√5 + 3(√7))(2√5 + 3(√7))
4*5 + 6√35 + 6√35 + 9*7
20 + 12√35 + 63
20 + 63 + 12√35
83 + 12√35
So you have 85 pages and 10 days.
You would do 85/10 to get 8.5 pages each day. Hope that’s right !
The answer is 4.2. Have a good day
