Answer:
-4√(5√(5
Explanation:
Lets work with 3√20 first
√20 can be simplified into 2√5 because if you factor √20 you will get 2,2, and 5= √2x2x5. Since radicals are the opposite of squaring you can take 2 of the 2's and put them outside the radical to get 2√5.
10x3√20
Using our simplified version of 3√20 from before, we can plug this in so it would be 10x2√5. Multiplying radicals you only need to multiply the base. The base is 2. 10x2 is 20 so this section will be simplified into 20√5.
-2√(10x3√(20
We plug in the simplified version of what we had from before again so it would look like -2√(20√(5. Now all we need to do is simplify the 20 in there. We do the same process again √2x2x5 and get 2√5. The 2 from 2√5 will multiply with -2 from the outside so your answer should be -4√(5√(5
-4√(5√(5
