Use demoivre's theorem to write the complex number in standard form.

A

Step-by-step explanation:

First express + i in trig form

| z | = = = 2

Θ = ( ) = ( 1) =

Thus

+ i = 2 [ cos + isin ]

Hence

( + i )³

= 2³ [ cos ( × 3) + isin( × 3 ) ]

= 8 [ cos( ) + isin() ] → A

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
