Answer:
2√5 * 4√5 = 40
Step-by-step explanation:
There are many ways that you can solve this problem. One way is by multiplying the base numbers first, then multiply the radicals, and finally multiplying your two results.
2√5 * 4√5
First, you can multiply 2 by 4.
2 * 4 = 8
Then, you can multiply √5 by √5.
√5 * √5 = √25 = 5
Finally, we multiply 5 by 8 to get the final answer.
5 * 8 = 40
So, 2√5 * 4√5 = 40
