- (5*18)*(5*16)*(5*14)*(5*12)*(5*5*2)*(5*8)*(5*6)*(5*4)*(5*2)=total number f 5 s=10

- 5*18*5*16*5*14*5*12*5*10=(5*2)*5*8*5*6*5*4*5*2=total number f 5 s=10
option 1; - 10 years agoHelpfull: Yes(4) No(0)
- Select the no of 5
5^10 - 10 years agoHelpfull: Yes(2) No(0)
- U can divide the above product completely only by ten 5s in the denominator. So answer is 10.

- 9*10 *8*10 *7*10 *6*10 *5*10 *4*10 *3*10 *2*10 *10
so as we have 9 tens clearly we can say we have 9 fives and one more 5 from 50
so totally 5^10 - 8 years agoHelpfull: Yes(0) No(0)
