Question 1044935
3x-y=12, then 8 to the power of x divided by 2 to the power of y equals what?
<pre>This is a question from the redesigned SAT. 
3x - y = 12_____y = 3x - 12
{{{8^x/2^y}}}______{{{(2^3)^x/2^y}}}______{{{2^(3x)/2^y}}} ------- Changing base 8 to base 2
{{{2^(3x)/2^(3x - 12)}}} ------- Substituting 3x - 12 for y
{{{highlight_green(2^(3x - (3x - 12)) = 2^(3x - 3x + 12) = highlight(2^12))}}}
