For any integer n 1 , the number of positive divisors of n is denoted by d(n) . Then, for a prime P, d (d (d(P)^7 ) ) is equal to

Step-by-step solution

Since, d(n) represents number of the divisors of n . array rlrl & d (P^7 ) =8 & d(8)= d (2^3 ) =4 & d(4)= d (2^2 ) =3 & d (d (d (P^7 ) ) ) =3 array
