Hello
Can someone explain to me how the final calculation in Example two is being calculated?
I have put a red circle around the part which I don't quite understand is being calculated. I am familiar with the "row[imath]\cdot[/imath]column" (dot product), however, it does not quite look like the dot product?
An example is [math]2\cdot5^k-3^k[/math]
When I do the dot product I get [imath]5^k\cdot2+0\cdot(-1)[/imath] where is the [imath]3^k[/imath] coming from?
