Ineed to complete a bunch of work by tomorrow, show your work if possible.

simplify

45m^2n^4

18m^4n^3

a. 5m^6n^7

2

b. 5nm^2

c. 5n^2

2 m

d 5n

2m^2

(5n) / m^2

Step-by-step explanation:

45m^2n^4

18m^4n^3 may be factored into m, n and constant terms:

45      m^2       n^4

 *  *

18        m^4       n^3

45/18 reduces to 5/2.  

m^2 / m^4 reduces to 1 / m^2.

n^4 / n^3 reduces to n.                                       5n

Multiplying these results together produces:  

                                                                              m^2

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
