Question

\[\sqrt{12}+4\sqrt{15}\]

Answer 1

\[\Huge 4\sqrt{15}+2\sqrt{3}\]

Answer 2

yup

Answer 3

how did you get that?

Answer 4

Calc.

Answer 5

well yeah, but how did you randomly get a two and a three?

Answer 6

let me solve

Answer 7

okay

Answer 8

\[\huge \sqrt{12} = \sqrt{4\times 3}=2\sqrt{3}\]

Answer 9

4x3 isnt the sq. root of 12?

Answer 10

you wont be getting the answer that way.

Answer 11

this is too confusing

Answer 12

Jocelyn, are you doing GCSE maths- surds?, If you are I can try and help you with this.

Answer 13

i dont know what that is

Answer 14

\[\huge \sqrt{12} = \sqrt{4\times 3}=\sqrt{2 \times 2 \times 3}=2\sqrt{3}\]

Answer 15

now can you get it?

Answer 16

Basically, what you want to do is get √12 and find 2 numbers that times together to get 12, for example- saifoo.khan did √4×3 - 4 x 3 = 12.
Then once you have that, you must find the square root of a square number, which in this case is 4.
Take the 4 and find the square root, which is 2, and thats the 2√3

Answer 17

okay, the explanation helped a bit.... thanks (:

Answer 18

so would my answer be \[2\sqrt{3}\]

Answer 19

no the answer will be my first post.

Answer 20

4√15 +2√3, saifoo's first answer given.

Answer 21

okay...
