$log_{3}( {2x}^{4} + 8 {x}^{3} ) - 3 log_{3}(x) = 2 log_{3}(x) \\ = log_{3}( \frac{2 {x}^{4} + 8 {x}^{3} }{ {x}^{3} + {x}^{2} } ) \\ = log_{3}( \frac{2 {x}^{2} + 8x}{x + 1} )$

Mathematics

Step-by-step explanation:

There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.

Now, we can substitute this into the ratio of teachers to students:

teachers : students = 3 : 35

teachers : (male students : female students) = 3 : (10 : 25)

Then the number of teachers is seen to be 3/25 of the number of female students:

(3/25)(500) = 60 . . . teachers
