- 54000 = 2^1 * 3^3 * 10^3
to make it ps * 2^2 or 4 - 10 years agoHelpfull: Yes(15) No(1)
- here 54000 is given means 54 * 10 * 10 * 10
it can also be written as 2* 3*3*3*10*10*10
to make it perfect cube every number must be three times so 2*2 is required
04 is the ans..... - 10 years agoHelpfull: Yes(9) No(0)
- it is 4.As when 4 multiplied by 54000 i.e 4*54000=216000 which is cube of 6.so
a)04(ans) - 10 years agoHelpfull: Yes(2) No(0)
- 4 is the answer 54000=3^3*4^2*5^3 so multiplied by 4 to be perfect square
- 10 years agoHelpfull: Yes(1) No(0)
- answer is 04(a);
because 54000----2^4*3^3*5^3.....the power of prime factors should be devisible by 3 for perfect cube hence here power of 2 only is not divisble by 3...i.e 4 so for divisble with 3 we have to multiply with 2^2 i.e 4 ..... - 9 years agoHelpfull: Yes(0) No(0)
- 4 , because 54000*4=216000 whos cubr root is 60
- 8 years agoHelpfull: Yes(0) No(0)
- (10^3) * (3 * 3 * 3) * 2 * 4 = perfect cube
- 6 years agoHelpfull: Yes(0) No(0)
- 4
54000*4=216000=(60)^3 - 6 years agoHelpfull: Yes(0) No(0)
- ans a 54000*04=2,16,000=(60)^3
- 5 years agoHelpfull: Yes(0) No(0)
