In week 3 of precalc 11, we learned about multiplying radicals by radicals. We practise doing this and then simplifying the equation. let’s use this for example

In an equation like this, you can multiply the radicals inside the bracket by the radical outside of the bracket. To solve the equation, do that and then simplify further from there.

From here you can’t really simplify it any further. Now you can also do the same thing with a mixed radical. Let’s use a more complicated equation

Now we start by simplifying everything in the brackets, then multiply by the mixed radical outside of the brackets.

we can’t simplify after this point.
