John has only 10000$. How many wine bottles of each type, John must buy?

A four-digit number (not beginning with 0) can be represented by ABCD. There is one number such that ABCD=A^B*C^D, where A^B means A raised to the B power. Can you find it?

You have $100 with you and you have to buy 100 balls with it. 100 is the exact figure and you can’t go below or above the numbers and you have to use the entire $100. If there is no kind of tax applied how many of each of the following balls will you be able to buy:

Green Balls costing $6
