Hi guys,

I have an equation y = a*b + c*d

The variables are just real numbers. How can I get this equality to hold without multiplying anything together? I have tried taking the log of each side but that doesn't work.

Anyone have any thoughts?

Hllo, sfspitfire23!

Are you sure of the wording of the problem?

I don't think it can be done.

It might help if we knew whatthis problem came from.*course*

If the variables were natural numbers, the task can be completed.

But withnumbers . . . I see no way to rewrite*real*

Just a linear algebra course. My teacher wants to know whether it can be done. I don't think it can.
