If $a$ and $b$ are whole numbers from $1$ to $100$, how many pairs of numbers $(a,b)$ are there which satisfy $a^{\sqrt{b}}=\sqrt{a^b}$
This was from a math contest I did earlier today and I was completely stumped how to solve this!
Other than the trivial $a=1=b$ and when $b=4$ then $a \in [1,100]$
Which means there are $101$ cases but are there any more?
