Question

Combine the following expressions.

Answer 1

?

Answer 2

too much work for me right now, are you doing flvs?

Answer 3

Look inside the radicals for multiples you can take the square root of to simplify the radical... i.e. sqrt(48) = sqrt(16*3) = sqrt (16) * sqrt (3) = 4 sqrt (3).

Then combine like terms

Answer 4

5x√3x?

Answer 5

@Scott* ?

Answer 6

The first expression is
\[3\sqrt{27x ^{3}}\]
This is equal to
\[3\sqrt{9* 3x ^{3}}\]
you can then pull a 3 out to get
\[3*3\sqrt{3x ^{3}}\]
or
\[9\sqrt{3x ^{3}}\]

Now try that same thing for the 2nd term, and then see if you can add them.

Answer 7

Then 2nd expression simplifies from
\[-2\sqrt{12x ^{3}}\] to \[-2\sqrt{4*3x ^{3}}\]
Then to
\[-2*2\sqrt{3x ^{3}}\]
to
\[-4\sqrt{3x ^{3}}\]
You can now add
\[9\sqrt{3x ^{3}} + -4\sqrt{3x ^{3}}\]
Answer = \[5\sqrt{3x ^{3}}\]
