In Q. No. 7, HCF `(a ,\ b)` is `p q` (b) `p^3q^3` (c) `p^3q^2` (d) `p^2q^2`

In Q.No.7,HCF(a,b) is pq(b)p^(3)q^(3)(c)p^(3)q^(2) (d) p^(2)q^(2)

If two positive integers a and b are expressible in the form a=p q^2 and b=p^3q ; p ,\ q being prime numbers, then LCM (a ,\ b) is (a) p q (b) p^3q^3 (c) p^3q^2 (d) p^2q^2

If two positive integers a and b are expressible in the form a =pq^2 and b=p^3q , p and q being prime numbers, then HCF (a,b) is a)pq b)p^3q^3 c)p^3q^2 d)p^2q^2

If two positive integers a and b are expressible in the form a=pq^(2) and b=p^(3)q;p,q being prime numbers,then LCM(a,b) is pq( b) p^(3)q^(3) (c) p^(3)q^(2)( d )p^(2)q^(2)

If A be one A.M. and p ,q be two G.M. ' s between two numbers, then 2A is equal to (a) (p^3+q^3)/(p q) (b) (p^3-q^3)/(p q) (c) (p^2+q^2)/2 (d) (p q)/2

If A be one A.M. and p ,q be two G.M. ' s between two numbers, then 2A is equal to (a)(p^3+q^3)/(p q) (b) (p^3-q^3)/(p q) (c) (p^2+q^2)/2 (d) (p q)/2

If two positive integers m and n are expressible in the form m=pq^(3) and n=p^(3)q^(2), where p,q are prime numbers, then HCF(m,n)=pq(b)pq^(2)(c)p^(3)q^(3)(d)p^(2)q^(3)

In a G.P. if (2p)^(t h) term is q^2a n d(2q)^(t h) term is p^2 where q in N , then its (p+q^(t h)) term is p q b. p^2q^2 c. 1/2p^3q^3 d. 1/4p^3q^3

In a G.P. if (2p)^(t h) term is q^2a n d(2q)^(t h) term is p^2 where q in N , then its (p+q^(t h)) term is p q b. p^2q^2 c.1/2p^3q^3 d. 1/4p^3q^3

If zeros of the polynomial f(x)=x^3-3p x^2+q x-r are in A.P., then (a) 2p^3=p q-r (b) 2p^3=p q+r (c) p^3=p q-r (d) None of these
