If abc < 0 and bcd > 0, which of the following is definitely negative ?
A. \(a^2b^3c^3d\)
B. \(a^2b^4c^4d^2\)
C. \(a^3b^4c^5d\)
D. \(a^3b^4c^4d\)
E. \(a^3b^5c^4d^2\)
A. \(a^2b^3c^3d\)
B. \(a^2b^4c^4d^2\)
C. \(a^3b^4c^5d\)
D. \(a^3b^4c^4d\)
E. \(a^3b^5c^4d^2\)
EDIT: Made a big mistake initially.
abc<0 and bcd>0
Divide both equations by bc then:
a<0 and d>0
If we divide both equations by -bc then:
a>0 and d<0.
So it shows a,d have opposing signs, so their product if both raised to odd powers will always be negative.
Option D perfectly portrays this.
