Let a and b be relatively prime integers with a>b>0 and 3(

Let S be the set of all points ((a)/(b),(c)/(d)) on the circle with radius 1 centred at (0,0) where a and b are relatively prime integers, c and d are relatively prime integers (that is HCF (a, b) = HCF (c,d) = 1), and the integers b and d are even. Then the set S

The real value of x satisfying ""^(3)sqrt(20x +^(3)sqrt(20x+13))=13 can be expressed as a/b where a and b are relatively prime positive integers. Find the value of b ?

If a and b are relatively prime numbers,then what is their HCF?

If a and b are relatively prime numbers,then what is their LCM?

Seven digits from the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 are written in random order. Let the probability that this number is divisible by 9 be p=a/b . Where a, b are relatively prime positive integers, then the value of a + b is ……….

For let h(x)={(1)/(q) if x=(p)/(q) and 0 if x is irrational where p&q>0 are relatively prime integers 0 then which one does not hold good?
