Question 112426
There are some possible ambiguities in the way you posed the question, but I'm going to assume you meant:


{{{(16/-2)*((-4)/4(2^3))}}}


Start by raising 2 to the 3rd power:  2 X 2 X 2 = 8.


{{{(16/-2)*((-4)/(4*8))}}}


And 4 X 8 = 32, so:


{{{(16/-2)*((-4)/32)}}}


16 divided by -2 is -8, so:


{{{-8*((-4)/32)}}}, and


32 divided by -4 is -8, so:


{{{-8*(1/-8)}}}


And finally, since {{{a*(1/a)=1}}} for all a:


{{{-8*(1/-8)=1}}}
