Question

USe an example to show that (k+m)u=ku+mu

Answer 1

i was thinking: why not just use dummy variables, like k=10, i=9 and m=3, but is there something deeper?

Answer 2

Nope, that is the correct course of action. That would be the only way to prove by example.

Answer 3

i was thinking that it was MUCH more complex than that..

Answer 4

If (k + m)u = ku + mu , you should be able to set variables k,m and u equal to any random numbers and both sides should come out equal.

Answer 5

I doubt if it is any more complex than that.

Answer 6

this was simple.
to me, simple means secretly hard. thank you for clarifying
