If `x=a^2.b^3`, where a and b are prime factors of x, then no. of factors of x is

If x=a^2.b^3 , where a and b are prime factors of x, then numbers of factors of x is _______

a and b are two positive integers such that the least prime factor of b is 3 and the least prime factor of b is 5. Then, the least prime factor of (a + b) is:

If 3 is the least prime factor of number a and 7 is the least prime factor of number b, then the least prime factor of a+b , is

If n is a natural number and n=p1x_(1)backslash p2x_(2)backslash p3x_(3), where p_(1),backslash p_(2),backslash p_(3) are distinct prime factors,then the number of prime factors for n is x_(1)+x_(2)+x_(3)(b)x_(1)+x_(2)+x_(3)(c)(x_(1)+1)(x_(2)+1)(x_(3)+1) (d) None of the above

If n is a natural and n=p_1^(x_1)p_2^(x_2)p_3^(x_3)," where "p_1,p_2,p_3 are distinct prime factors, then the number of prime factors for his

if 3 is the least prime factor of number a and 7 is the least prime factor of number b,then the least prime factor of a+b, is
