Answer: 100√6
Step-by-step explanation:
Start out by multiplying the 2 by the 10 to get 20.
Then, multiply √5 and √30 together to get √150. The largest perfect square within √150 is √25 (don't forget about your √6)
√25 is 5. Multiply your 20 and 5 together to get 100, and then put your √6 next to the 100 since it cannot be added or multiplied since they are not like-terms.
Thus, leaving you with an answer of 100√6.
