How do you simplify #8 sqrt (19s) - 8 sqrt(10d) - 4 sqrt( 19s) - 8 sqrt (10d)#?
Let's first look at the terms within the square roots themselves:
There is nothing within the roots that can be simplified - no squares under the root that can be extracted (unlike, for example,
So what we're really talking about here is two complicated looking terms:
which gets us:
which gives us:
and now we can put in the original terms:
