Question

dividing monimials 7c^7/-7c^2

Answer 1

Divide the number parts: 7/(-7)
To divide the variables, use the rule of dividing powers:
a^m/a^n = a^(m - n)
For example:
28a^5/-4a^2 = -7a^3

Answer 2

7 and 7 get cancelled, but the negative sign remains...
then since c is common, u subtract the powers...7-2 = c^5..

Answer 3

-c^5

Answer 4

-c^5 is the right answer
