P+ b= 207
p-59= b
P+ (P-59)=207
2p-59=207:
2p =207+59
p=266/2
P=133
b=133-59
b=74
psych books= 133
biology books= 74
74+133= 207(Check)
Given:
The expression is
To find:
The simplified form of the given expression.
Solution:
We have,
It can be written as
Taking LCM, we get
Cancel out the common factors.
Therefore, the simplified form of the given expression is .
First, replace
and
. Then you have
If we take
, then immediately we see a differential in the numerator in the form of
. So the integral becomes
and evaluates to
making (A) the correct answer.

Explanation: Eukaryotes along with some prokaryotes also perform the process of photosynthesis. Photosynthesis needs chloroplast and it is also found in some of the prokaryotes.
Prokaryotes are primitive cells but they do have organelles like mitochondria and chloroplast.
Photosynthesis is the process by which glucose is made in the presence of sunlight out of which oxygen is released into the environment and carbon dioxide from the environment is used.
