14SQRT 32 WITH CUBE4 ON THE TOP SUBTRACTED BY 15 SQRT 162 WITH CUBE4 ON THE TOP
:
I have no idea what you mean by "Cube4" so ignoring that perhaps this will help on the radicals:

14%2ASqrt%2832%29 - 15%2ASqrt%28162%29
:
Find the factors that are perfect squares inside the radical, you can write it:
14%2ASqrt%2816%2A2%29 - 15%2ASqrt%2881%2A2%29
:
Extract the squares from those:
14%2A4Sqrt%282%29 - 15%2A9Sqrt%282%29
:
Both expression have Sqrt(2) so just do the math:
56%2ASqrt%282%29 - 135%2ASqrt%282%29 = -79%2ASqrt%282%29

This does not seem to make much sense, look at the way other students submit these problems and resubmit it; perhaps we can understand exactly what you want.
