If a lies in the range (-5,4) then which of the following statements must be true?	Choose one.
A) a^4 >a^3 > a^2 > a B) a > a^2 > a^3 > a^4 C) a^4 > a^2 > a^3 >a D) a^2 > a^4 > a^3 >a E) a^2 > a^4 > a > a^3
consider any number from the given range (-5, +4)..let a=-1/2   then a^2= 1/4   a^3=-1/8   a^4=1/16   so we have a^2&gt;a^4&gt;a^3&gt;a   Ans a^2 &gt; a^4 &gt; a^3 &gt;a
<result>D</result>
