Question 730763
.
what expression is equivalent to (-2)^8 
a.[(-2)^4]^4 or b.[(-2)^5]^3
~~~~~~~~~~~~~~~~~~~~~~~~~~~



        This question is a  TRAP.


        NO ONE option  (a)  or  (b)  is a correct answer.



<pre>
Indeed, {{{(-2)^8}}} = {{{2^8}}} = 256.


In case (a),  [(-2)^4]^4 = 16^4 = 65536.


In case (b), [(-2)^5]^3 = (-32)^3 = -32768.


So, neither (a) nor (b) is the correct value.

Solved.
