Answer:
.
Step-by-step explanation:
To find .
First, calculate the corresponding indefinite integral:
Integrate term by term:
Apply the constant rule
Apply the constant multiple rule
Apply the power rule
Therefore,
According to the Fundamental Theorem of Calculus, , so just evaluate the integral at the endpoints, and that's the answer.
Lets say that the two unknown integers are
and
.
We know the following things about
and
:
And, we want to find
.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:
So, given what we know about the unknown integers, the previous can be written as:
We can easily solve for
:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of
and
, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.

Answer:
Sage is correct
Step-by-step explanation:
1 1/2/1/3 = 3(1 1/2) = 4 1/2
another way:
3/2 ÷ 1/3 = 3/2 x 3/1 = 9/2 = 4 1/2
