@techsurge said:Find number of real solutions of log_base9_(2x^2+3x+1) = log_base3_(x-3)
Constraints:
2x^2 + 3x + 1 > 0 and x -3 > 0
(2x +1)(x+1) > 0 and x > 3
x > 3
Now,
2x^2 +3x + 1 = (x - 3)*(x-3)
=> 2x^2 + 3x + 1 = x^2 - 6x + 9
=> x^2 + 9x - 8 = 0 => Both rejected
0 solutions !?
@krum said:all 3 digit numbers i.e 900
prime factors 
. i read it as factors 
. and dat was one insurmountable task !!

infinite ??
@krum said:log9a=log3b=k=>a=k^9, b=k^3so a=b^3galat hai kya?
2x^2+3x+1=m
x-3=n
log(m)/log(3^2)=log(n)/log3
logbase3(m)=2 logbase3(n)
now it will becm square on RHS
x-3=n
log(m)/log(3^2)=log(n)/log3
logbase3(m)=2 logbase3(n)
now it will becm square on RHS
@krum said:how many 3 digit natural numbers have less than 5 prime factors?
sabhi 3 digit no honge aise to...
minimum no which can have 5 prime factor
= 2*3*5*7*11 = 2310
which is digit no

Not possible. infinite jumps
There are 8 poles on the same side of a striaght road. Two of these poles are without flags, two have same country flag, 4 of them have plain flags but of different colour, What is the probability that first four poles from either end have two flags of the country and 2 plain colored flags ??

(4c2*4!/2*4!/2*2)/(8!/4)
=6/35

1/70
[ (4!*4!/ 2!*2! )/(8!/2!*2!)] = 1/70
prob vale kabhi sahi nai hote mere

By applying area = na^2/4Cot(pie/n) = 500/4Cot36
