@pakkapagal said:Q3:find the number of divisors of 15!
15! equal to 2^11*3^6*5^3*7^2*11*13
so no divisors equal to 12*7*3*2*2
4032
so no divisors equal to 12*7*3*2*2
4032

ha jo like kiye vo....galat tarike se diye ..ek saath dene the :(
Find n in n!=3!*5!*7!
options 8,9,10,11...getting 10 but its not correct :(
@pakkapagal said:Find n in n!=3!*5!*7!options 8,9,10,11...getting 10 but its not correct
n! = (3*2)*(5*2^2*3*2)*(7*3*2*5*2^2*3*2) = 2^8*3^4*5^2*7
cannot be 11...has to be 10 (8th power of 2, 4th power of 3)....answer given must have been wrong IMO...it has to be 10...
totalgadha ki ebook ka hai...81 question..:/

arre 10 hi h!!
3*2*1 * 5*4*3*2*1 * 7!
10*9*8*7! = 10!
even if u multiply n see... it comes out to be 10! only.
3*2*1 * 5*4*3*2*1 * 7!
10*9*8*7! = 10!
even if u multiply n see... it comes out to be 10! only.
