Question 378290
<pre>
{{{ ( (1/2)^3 - (1/4)^2 )  *  2^3  }}}

Use {{{((numerator)/(denominator))^N}}}{{{""=""}}}{{{(numerator^N)/(denominator^N)}}}

{{{ ( (1^3)/(2^3) - (1^2)/(4^2) ) * 2^3 }}}

{{{1^3=1*1*1=1}}}, {{{2^3=2*2*2=8}}}, {{{1^2=1*1=1}}}, {{{4^2=4*4=16}}}

{{{ ( 1/8 - 1/16 ) * 8 }}}

Write the {{{1/8}}} as {{{2/16}}} so it will have the same denominator as {{{-1/16}}}

{{{ ( 2/16 - 1/16 ) * 8 }}}

{{{ ( 1/16 ) * 8 }}}

{{{8/16}}}

{{{1/2}}}
