Can you think of two no.s which doesnot contain zeros at the end

but whose product results in 1000000. How many such possible no.s are

there?

2*2*2*2*2*2*5*5*5*5*5*5=64*15625=1000000   only possible way for making combination of all factors without any 0's is 64*15625    dance1w

Hello rahul:

Simple description as follow:

10^6 = 2^6 * 5^6

Number of possible combinations excluding zeros [tens] at the end of each integer is, 6!*6!-3! (first 6! came from 2^6, second from 5^6 and the third came from the combination of this two as 10's)

So, number of combination of forming 10^6 excluding 10's = 518394

This number with including repeating events too.

question is "any 2 numbers that dosent contain any zeros at the end"  not "the combinations without using 10's"  The only possible way is 64*15625

Thanks, But this question also include: Can you think of two no.s which doesnot contain zeros at the end

but whose product results in 1000000. "How many such possible no.s are there?"[/color]

here such refers to possible combination without any 0's at the end of two numbers that should be multiplied...  I guess its clear now ?

the only solution  is 15625 and 64.

 

  (15625*64)=1000000
