N is a natural number and n^3 has 16 factors. Then how many factors can n^4 have?
Read Solution (Total 8)
-
- solve by using prime factorization
consider a term 6.
6^3 -> can be written as -> 2^3 * 3^3
then by factor rule , (3+1)*(3+1)=16
therefore,
6^4=(2^4)*(3^4) ---> (4+1)*(4+1) = 25
Ans: 25

- 21 or 25
m+1=16 (m+1)(n+1)=16
m=15 (m+1)(n+1)= 4*4
a^15=N^3 m= 3 n= 3
N=a^5 a^3*b^3= N^3
N^4=a^20 a*b= N
factors=21 a^4*b^4= N^4

- if n=6 then n3 = 216 so n = 6 and 216which is having 3 3's and 3 2's so n4 = 1296 which is having 4 2's and 4 3's so factors equals to 25

- m+1=16.
a^15=n^3
n=a^5
n^4=a^20
no: of factors is 21 - 11 years agoHelpfull: Yes(4) No(1)
- (3+1)(3+1)=16..this is for n^3..for n^4 it will be (3+1+(3/3))(3+1+(3/3))=5*5=25

- n=6 and n^4=6^4=(2*3)^4=5*5=25

- lets take n as 8
then 4^3*2^3=(3+1)*(3+1)=16 factors
same as 4^4*2^4=(4+1)*(4+1)=25 factors
whatever may be the value of n just apply this method - 11 years agoHelpfull: Yes(1) No(0)
- 21 will be the correct answer !!!
