(7√3 + 4√3) + (- 4√6 - 3√6)
11√3 - 7√6

Answer 15

i don't understant

Answer 16

*understand

Answer 17

basically \[7\sqrt3 - 4\sqrt6 +\sqrt(16*3)-\sqrt(9*6)=7\sqrt3 - 4\sqrt6 +\sqrt16 *\sqrt3 - \sqrt9 *\sqrt 6\]

Answer 18

just have to break down the ones that can still be simplified

Answer 19

how do i do that?

Answer 20

so you saw that you had sqrt54 the sqrt of 54 would be simplified by using sqrt9*6 because that equals that. then the sqrt9 can be alone because the sqrt of 9 is three however with 6 you cannot simplifie it any more

Answer 21

okay so the answer would be c?

Answer 22

Answer 23

@gabgurl

Answer 24

B because it all simplifies to

7√3 - 4√6 + 4√3 - 3√6 =
(7√3 + 4√3) + (- 4√6 - 3√6)
11√3 - 7√6

so \[11\sqrt3 -7\sqrt6\] so b is your answer

Answer 25

oh okay thank you
