If a+b+c=0, then which of the following are correct? 1. a^(3) + b^(3) + c^(3) = 3abc 2. a^(2) + b^(2) + c^(2) = -2(ab + bc + ca) 3. a^(3) + b^(3) + c^(3) = -3ab(a+b) Select the correct answer using the code given below

If (2a+3b) (2c -3d) = (2a-3b) (2c+3d) then

For reaction A + 3B to 2C + D Which one of the following is not correct ?

If (a)/(b)=(b)/(c)=(c)/(d), then (b^(3)+c^(3)+d^(3))/(a^(3)+b^(3)+c^(3)) will be equal to (a)/(b) b.(b)/(c) c.(c)/(d) d.(d)/(a)

log((a^(3)*b^(3))/(c^(3)))+log((b^(3)*c^(3))/(d^(3)))+log((c^(3)*d^(3))/(a^(3)))-3log(b^(2)c)

log((a^(3)*b^(3))/(c^(3)))+log((b^(3)*c^(3))/(d^(3)))+log((c^(3)*d^(3))/(a^(3)))-3log(b^(2)c)

If a,b,c,d are in continued proportion,then (a^(3)+b^(3)+c^(3))/(b^(3)+c^(3)+d^(3))=(i)(a)/(b)(ii)(b)/(c)(iii)(c)/(d)(iv)(a)/(d)

If (2a+3b)(2c-3d)=(2a-3b)(2c+3d) then (a)/(b)=(c)/(d)( b) (a)/(d)=(c)/(b)( c) (a)/(b)=(d)/(c)(d)(b)/(a)=(c)/(d)

If (a)/(b)=(c)/(d) then (a+b)/(a-b)=(c+d)/(c-d),ab=cd ,(a^(2)+b^(2))/(a^(2)-b^(2))=(c^(2)+d^(2))/(c^(2)-d^(2)), ad-dc=0
