Question

simplify the expression √6 + 2√6

Answer 1

I can take a crack at it if you like. Give me a minute! :)

Answer 2

I believe you use the distributive property observed here: http://hotmath.com/tutor/?pid=genericalg1_8_1_RadicalExpressionsandRadicalEquations_15_700&gt_index=genericalg1:8:1:7

Answer 3

Does this look familar?

Answer 4

sorry! thats as much as i know :(

Answer 5

its basically where you add the two numbers in front of the radical because they are like terms. if that makes sense. there is a understood 1 in front \[\sqrt{6} \]. its like when you add 2x and 4x. but you cannot add for example. \[2x ^{2} \] and 2x. These share the common term of radical 6.

Answer 6

ok, what dont you understand? ill try my best to answer!

Answer 7

Ok. you are using the distributive property. It looks like this:
\[a \sqrt{b}+c \sqrt{b}=(a+c)\sqrt{b}\]
Do you understand this?

Answer 8

ok! you use it like this for this equation.
\[1\sqrt{6}+2\sqrt{6}=(1+2)\sqrt{6}\]

Answer 9

you had it right the first time! D:

Answer 10

Nooo. i just meant that i couldnt explain WHY thats the answer.

Answer 11

Im sorry. that is the correct answer.

Answer 12

I hope this helped a little :( there is some great exercises online for these types of equations if you need it.
