Question

what is 2√108

Answer 1

20.784

Answer 2

simplified

Answer 3

bring 2 inside the square root
\[2=\sqrt{4}\]
the \[\sqrt{4*108}=\sqrt{432}=20.78\]

Answer 4

get it?

Answer 5

A: 12√3
B: 6√3
C: 144√3
D: 8√3

Answer 6

your job is to look for perfect squares that are factors of 108

Answer 7

I dont know how to do that.

Answer 8

since it is divisible both by 4 and by 9, it is divisible by 36

Answer 9

in fact, \(108=36\times 3\)

Answer 10

similar if you take out of the square root
\[\sqrt{432}= \sqrt{144*3}=12\sqrt{3}\]

Answer 11

so
\[\sqrt{108}=\sqrt{36\times 3}=\sqrt{36}\sqrt{3}=6\sqrt{3}\]

Answer 12

if your question is
\[2\sqrt{108}\] then the answer would be
\[12\sqrt{3}\]
