2) p=7


1) \(m^4*np=2,835\)

\(m^4*n*p = 3^4*5*7\)

\(n*p\) can be ---> (1*56), (5*7), (7*5),(56*1) Insufficient.

2) p=7 Clearly insufficient.

(1)&(2) Sufficient at first glance but we should not forget about \(1\). \(m^4\) can bee either \(3^4\) or \(1^4\) ---- \(1^4*2835\) or \(3^4*56\). Still insufficient.

Answer E.

Could you, please, elaborate on where 1*56 and 56*1 pairs for n*p are coming from? To me m can be either 1 or 3, if it is 3 then n*p=5*7=35.If m is 1 then n*p=2,835. I don't see how n*p can equal 56...Thanks

Pay attention to special case in which m = 1!

2) p=7


The answer is E

Factorization of 2835 =3^4*5*7

But we are not told that n and p have to be prime so following cases are possible
1*3
35*1
5*7
7*5
So insufficient
p=7
it does not provide information for other variable so insufficient

Together we know p=7 then n=5
Hence together they are sufficient
