Q). Number of prime factors in (216)^3 / 5 x (2500)^2 / 5 x (300)^1 / 5 is :
Option
1) 3
2) 4
3) 6
4) 7
Read Solution (Total 10)
-
- 3
solving it we get 216*3*100*2*60=216*6*6*1000
=6^5*10^3
so 2,3,5 are prime factors=3 - 10 years agoHelpfull: Yes(15) No(4)
- 216*3/5*2500*2/5*300*1/5
dividing by all 3 5
we get 216*3*100*2*60
now write it in prime factor format
2^8* 3^2*5^3*17^1
so prime factor will be 9*3*4*2=216
so 216 prime factors :) - 10 years agoHelpfull: Yes(5) No(13)
- ans is 3????
- 10 years agoHelpfull: Yes(2) No(0)
- solving it we get 2^8*3^7*5^3
so 2,3,and 5 are prime factors
so ans is 3. - 10 years agoHelpfull: Yes(2) No(1)
- 3 is ans...
- 10 years agoHelpfull: Yes(2) No(1)
- sorry above solution was wrong...
after solving we will get the prime factors as 2^8*3^5*5^3
so number of prime factors will be=9*6*4
216 - 10 years agoHelpfull: Yes(2) No(4)
- answer 3
3 factors are 3 ,2 no 5, - 9 years agoHelpfull: Yes(1) No(0)
- plz clearly xplain the ans
