There's nothing preventing us from computing one integral at a time:



Expand the integrand completely:

Then

4r^2=4 if r=1
2s^3=250 if s=5
Answer:
1408 multiply 64 by 22 for a total of 1,408
Given:
The equation is

The incorrect solution steps are given.
To find:
The first error.
Solution:
We have,

Using distributive property, we get


The given step 1 is
, which is not correct.
Therefore, there is first error in step 1 because the distribution property is not used properly.
Hence, the correct option is D.
8 is the greatest common factor
