Question

4√2 + 7√2 - 3√2
Can you show me how to do this?
Home schooled and don't understand this lesson.

Answer 1

Factor

Answer 2

sqrt(2)(4+7-3)= 8(SQRT(2))

Answer 3

as the value in under root is same so take them common
8underroot 2 is answer

Answer 4

Just add the numbers in front of the square root since they all have the same number inside the radical.. so it would be \[8\sqrt{2}\]

Answer 5

=√2(4+7-3) = 8√2

Answer 6

Thank you all, I understand it a lot better thanks to Tyler1992 for the good explanation. (:

Answer 7

That only works if they have the same number under the radical though.. But you're welcome.
