Equation `x^(n)-1=0,ngt1,ninN,` has roots `1,a_(1),a_(2),...,a_(n),.`
The value of `(1-a_(1))(1-a_(2))...(1-a_(n)),` is

Equation x^(n)-1=0,ngt1,ninN, has roots 1,a_(1),a_(2),...,a_(n-1),. The value of (1-a_(1))(1-a_(2))...(1-a_(n-1)), is

Equation x^(n)-1=0, ngt1, n in N," has roots "1,a_(1),a_(2),…,a_(n-1). The value of (1-a_(1))(1-a_(2))…(1-a_(n-1)) is

Equation x^(n)-1=0, ngt1, n in N," has roots "1,a_(1),a_(2),…,a_(n-1). The value of sum_(r=1)^(n-1) (1)/(2-a_(r)) is

If roots of an equation x^(n)-1=0 are e1,a_(1),a_(2),.....a_(n-1), then the value of (1-a_(1))(1-a_(2))(1-a_(3))(1-a_(n-1)) will be n b.n^(2) c.n^(n) d.0

Q.if a_(1)>0f or i=1,2,......,n and a_(1)a_(2),......a_(n)=1, then minimum value (1+a_(1))(1+a_(2)),...,,(1+a_(n)) is :

If a_(i)gt0 for i u=1, 2, 3, … ,n and a_(1)a_(2)…a_(n)=1, then the minimum value of (1+a_(1))(1+a_(2))…(1+a_(n)) , is

. If a_(1),a_(2),a_(3),...,a_(2n+1) are in AP then (a_(2n+1)+a_(1))+(a_(2n)+a_(2))+...+(a_(n+2)+a_(n)) is equal to

If a_(1),a_(2),...a_(n) are in H.P then the expression a_(1)a_(2)+a_(2)a_(3)+...+a_(n-1)a_(n) is equal to

If a_(1)=2 and a_(n)-a_(n-1)=2n(n>=2), find the value of a_(1)+a_(2)+a_(3)+....+a_(20)
