Simplify all of the below
1.) 3√10+7√15-6√10-4√15
2.)5√7+12√6-10√7-5√6
3.)7√3-4√6+√48-√54
4.)3√5-2√7+45-√28
5.) √10 * √8

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
