The induction step:
Assume that 10 divides .
Want to show for n+1, 1.e want to show that 10 divides
Let see if you can go from here............
Here's another one and not sure what to do with the exponents on this... Prove the if 0<a<b then a^(1/n) < b^(1/n) for n in N. Or how to show for n + 1.
Oh nm this would be nth roots so prove by contradiction... sorry I answered my own question..
