* 2.3 ^5 log(is raised at the same level as 5 meaning not above 5) base 2.3 ^1 The answer is 1 but I do not get how?

*If p and q are two different prime numbers greater than 2, and n=pq, how many positive factors, including 1 and n, does n have? Do not get how the answer is 4.

even factors of 4*5 =20

so the factors are 1, 2 ,4 ,5 ,10 ,20

among them 2,4,10,20 are even.

here 4 is the minimum no of +ve factors.

n will have the factors,

=1*n

=p*q

including 1 and n, n have minimum 4 factors.

it could be more.

***for Q2 I have not understood.
