Question

simplify:

Answer 1

\[\sqrt{72}-\sqrt{147}-5\sqrt{8}+3\sqrt{48}\]

Answer 2

a.-2sqrt35
b.sqrt5
c.-8+5sqrt6
d.-4sqrt2+5sqrt3

Answer 3

\[\sqrt{72}=\sqrt{36\times2}=6\sqrt{2}\]
\[\sqrt{147}=\sqrt{49\times3}=7\sqrt{3}\]
\[\sqrt{8}=\sqrt{4\times2}=2\sqrt{2}\]
\[\sqrt{48}=\sqrt{16\times3}=4\sqrt{3}\]
complete the answer.

Answer 4

ok give me onw minute to figure it out

Answer 5

I got D. -4sqrt2+5sqrt3
is that correct
@terenzreignz

Answer 6

Yup, it is :)

Answer 7

can you check one more for me in a minute please

Answer 8

\[6\sqrt[3]{5}-\sqrt[4]{5}+2\sqrt[3]{5}+4\sqrt[4]{5}\]

Answer 9

Good job.

Answer 10

a.11sqrt5
b.\[8\sqrt[3]{5}+3\sqrt[4]{5}\]
c.11sqrt10
d.\[8\sqrt[3]{10}+3\sqrt[4]{10}\]
i got A

Answer 11

is my answer correct @Jhannybean and @terenzreignz

Answer 12

Unfortunately no :)
Why complicate things? Just combine like terms :D

Answer 13

oh k i will try that

Answer 14

i am confused icombined like terms and my answer doesnt match any of my choices

Answer 15

\begin{align}
\large \sqrt{72}-\sqrt{147}-5\sqrt{8}+3\sqrt{48} &= \large 6\sqrt{2} - 7\sqrt{3} -5(2\sqrt{2})+3(4\sqrt{3}) \\
&=\large \color{red}{6\sqrt{2}} -\color{blue}{7\sqrt{3}} -\color{red}{5(2\sqrt{2})} +\color{blue}{3(4\sqrt{3})} \\
\end{align}

Answer 16

Match the colors, simplify the highlighted stuff.

Answer 17

ok thanks

Answer 18

i got\[8\sqrt[3]{10}+3\sqrt[4]{10}\]

Answer 19

@Jhannybean

Answer 20

\[\large \color{red}{6\sqrt{2}} -\color{blue}{7\sqrt{3}} -\color{red}{5(2\sqrt{2})} +\color{blue}{3(4\sqrt{3})}\]\[\large (6\sqrt{2}-10\sqrt{2})+(12\sqrt{3}-7\sqrt{3})\]Can you simplify this forme?

Answer 21

do i distribute?

Answer 22

No...just simplify what is inside the parenthesis. You cannot combine the stuff with the \(\sqrt{2}\) attached to them with \(\sqrt{3}\) unless you multiply them together, we're not using that operant here so combining them is not an option.

Think of \(\sqrt{2}\) and \(\sqrt{3}\) as x and y values. They cannot be combined here :)

Answer 23

Using colours to emphasise?
That's my play, @Jhannybean >:(

LOL JK

Answer 24

xD

Answer 25

-4sqrt2+5sqrt3

Answer 26

Good job : )

Answer 27

butthat isnt one of my answer choices

Answer 28

these are my answer choices;
a.11sqrt5
b.85 √ 3 +35 √ 4
c.11sqrt10
d.810 − − √ 3 +310 − −

Answer 29

d i supose to be
\[8\sqrt[3]{10}+3\sqrt[4]{}\]

Answer 30

and bis supose to be \[8\sqrt[3]{5}+3\sqrt[4]{5}\]

Answer 31

@Jhannybean

Answer 32

That's not even one of your answer choices...

a.-2sqrt35
b.sqrt5
c.-8+5sqrt6
d.-4sqrt2+5sqrt3

Answer 33

the only other one that has a radical in it is b so is that going to be my answer

Answer 34

you have radicals in all your solutions??

Answer 35

your looking at the first question i am doing the second one and i reposted the answer choices

Answer 36

Oh,sorry, i didn't see that one.

Answer 37

\[\large 6\sqrt[3]{5}-\sqrt[4]{5}+2\sqrt[3]{5}+4\sqrt[4]{5}\] For this one just combine like terms,once again. You got what answer?

Answer 38

i got d

Answer 39

i ment b sorry

Answer 40

\[8\sqrt[3]{5}+3\sqrt[4]{}\]

Answer 41

<_<... Lets work it out :P

Answer 42

\[\large (6\sqrt[3]{5}+2\sqrt[3]{5})+(4\sqrt[4]{5}-1\sqrt[4]{5})\]

Answer 43

And yes, you get \(\large 8\sqrt[3]{5} +3\sqrt[4]{5} \)

Answer 44

so im correct

Answer 45

Yes :)

Answer 46

thankss
