Answer:
100
Step-by-step explanation:
If it is divisible by ten, it has to end in 0, so you need a square ending in 0. Which is the smallest one? 100. Does it happen to be divisible by 4 and 5? Sure does:
100/4 = 25.
100/5 = 20.
So 100 is the smallest square ending in 0 and it is divisible by both 4 and 5, so there you have it.
