Question 60375: Hi, I am so lost in my math class...
48x^3 under the radical sign + x (outside of radical) 147x under the radical sign.
I have been trying this problem for quite a while.
I am thinking I need to break it up: 8 under radical + 6 under radical.
But since none of those goes into 147 evenly, I am stuck.
Any help would be appreciated! Thanks.
