The quantity (3^3)(4^4)(5^5)(6^6) ? (3^6)(4^5)(5^4)(6^3) will end in how many zeros?

could you solve this problem

There is a question mark in your expression which makes things confusing. I am assuming the expression is: 3455  66 / 34563

To find number of zeroes, we have to find the powers of 10 in an expression.

3455  66 / 34563  = 33 (22)4 55 36 26 / 36 (22)5 54 23 33 = 39 214 55 / 39 213 54 = 39-9 214-13 55-4 = 2*5 = 10

1 zero

sorry for that mistake its mjnus sign instead of question mark. can you reslove the problem.
