 Dividing Radical Expressions Radicals divide: 
The numbers in front divide separately: 
Sometimes they just reduce: 
The radicals divide separately: 
Just as with multiplication, numbers and radicals are divided or reduced separately. 
Sometimes there will be a little simplifying afterwards: 
Here 16 divides by 8, and both radicals divide by √2:  Notice that the answer still has a radical left, but it's in the denominator. When this happens, we have to continue simplifying using a technique called Rationalizing the Denominator, which we're dealing with separately. That's also where we'll look at dividing by binomial radicals. |
