Simplify?
12%5E3%2Asqrt%284x%29-10%5E3%2Asqrt%284x%29-6%5E3%2Asqrt%284x%29 First factor out the sqrt%284x%29
%2812%5E3-10%5E3-6%5E3%29%2Asqrt%284x%29 Now perform the indicated operations inside the parentheses.
%281728-1000-216%29%2Asqrt%284x%29
512%2Asqrt%284x%29 Finally, you could take the square root of 4 (that's 2) and multiply that by the 512 to get the final answer of:
