(3p-(1)/(6))^(3)

If x+(1)/(x)=p, the value of x^(3)+(1)/(x^(3)) is p^(3)+(1)/(p^(3))(b)p^(3)-3p(c)p^(3)(d)p^(3)+3p

Verify that ((3p )/( 7) + (7)/(6p )) ^(2) - ((3p)/(7) -(7)/( 6p ))^2=2

It is given that the events A and B are such that P(A)=(1)/(4),P((A)/(B))=(1)/(2) and p((B)/(A))=(2)/(3) Then P(B) is: (1)(1)/(6)(2)(1)/(3)(3)(2)/(3)(4)(1)/(2)

Name the element with the following electronic configurations . (a) 1s^(2)2s^(2) 2p^(6) 3s^(2) 3p^(1) (b) 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(1) (c ) 1s^(2) 2s^(1) 2p^(6) 3s^(2) 3p^(6) 3d^( 5) 4s^(1)

Name the element with the following electronic configurations . (a) 1s^(2)2s^(2) 2p^(6) 3s^(2) 3p^(1) (b) 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(1)

If (1+x+x^(2)+....+x^(p))^(6)=a_(o)+a_(1)x+a_(2)x^(2)+.......+a_(6p)X^(6p) ,then the value of : (1)/(p(p+1)^(6))[a+2a_(2)+3a_(3)+...+6pa_(6p)] is

1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(5) is not the electron configuration of
