Most logical thing to do with these exponents and sums?

Question

I'm doing homework for a programming class and came across this problem. There's no directions besides what I've shown, so I don't even know what it's asking me to do. What makes the most sense for what it's asking me to solve?

Answer 1

Hint

Use that $a^n\cdot a^m=a^{n+m}$ to simplify $a).$ You should obtain $x^{N(N+1)/2}.$

Use that $\log_a a^x=a^{\log_a x}=x$ to simplify $b),c),d).$ You should obtain $6,280$ and $N,$ respectively.

Answer 2

I think what are you supposed to do is to sinplify them. For example $$x\cdot x^2=x^3$$ So you could do the same thing for the first expression, then go on with the others.
