This month the Middle School Media newspaper has 25 pages. Twenty-five schools order the paper for each of their students. Each

Georgia [21]

Answer:

The total number of pages in all the newspaper is 390,625 pages

Step-by-step explanation:

The number of pages in the newspaper = 25 pages

The number of schools ordering the newspaper = 25 schools

The number of class rooms in each school = 25 classrooms

The number of students in each classroom = 25 students

Therefore;

The total number of pages in all the newspaper = 25 pages per paper × 25 schools × 25 classroom per school × 25 students per classroom

The total number of pages in all the newspaper = 25 × 25 × 25 × 25 = 25⁴

The total number of pages in all the newspaper = 25⁴ = 390,625 pages

Hello! :)

$\large\boxed{\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}}$

Find the derivative using the quotient rule:

$\frac{f(x)}{g(x)} = \frac{g(x) * f'(x) - f(x) * g'(x)}{(g(x))^{2}}$

In this instance:

$f(x) = e^{\frac{3}{x} }\\\\g(x) = x^{2}$

Use the following properties to find the derivative of f(x) and g(x):

$e^{u} = u' * e^{u}\\\\x^{n} = nx^{n-1}$

Use the quotient rule:

$\frac{x^{2} * (e^{\frac{3}{x}} * (-3x^{-2})) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}$

Simplify the numerator:

$\frac{(e^{\frac{3}{x}} * (-3)) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}$

Factor out $e^{\frac{3}{x}}$

$\frac{e^{\frac{3}{x}} (-3 - 2x )}{x^{4}}$

Factor out -1 from the numerator:

$\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}$

And we're done! Thanks for posting the question to my 1000th answer!
