Answer 2

10

Answer 3

How did you do that?

Answer 4

2 * sqrt(25) = 2 * 5 = 10

Answer 5

\[\sqrt{3}*\sqrt{18}\]

Answer 6

\[3\sqrt{6}\]

Answer 7

How do i simplify them do i factor them out first?

Answer 8

it doesnt matter. just multiply everything in the square root and then get squares out.
for example, sqrt(3) * sqrt(18) = sqrt(54). since 54 = 9 * 6 = 3^2 * 6, you know that you can take out the 3 in the sqrt(54) thus it becomes 3 * sqrt(6)

Answer 9

\[\sqrt{60x^4y^7}\]
