Hi, i've been solving some excersices but I am stuck with this one.
Proof by Mathematical Induction the following expresion
Well the first thing I did was rewrite the expesion as this:
then i proof this is true for p(1)
then I assume this true for p(k)
and then i did the sum
after this step I don't really know what to do for symplify the expression, so if can help it would be great and if i made a mistake in previous steps please make know. thanks
