If a lies in the range (-4,3) then which of the following statements must be true?
Choose the correct choice from the following
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 (-4,+3)..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>
