Question

Simplify: sqrt c (3 + 2sqrt 5)
5 sqrt 5c
C sqrt 3 + c sqrt 10
3 sqrt c + 2 sqrt 5c
3 sqrt c + 2c sqrt 5

Answer 1

Use distributive property
a(b+c)+ab+ac
Here
a=sqrtc
b=3
c=2sqrt5
Does that help? @Solmyr

Answer 2

srry had to do something

Answer 3

Sqrt c(3 + 2 sqrt 5) + sqrt c(3) + sqrt c(2 sqrt 5)

Answer 4

it is best to put the numbers in front of the sq rt sign, it's less confusing
Sqrt c(3 + 2 sqrt 5) = 3sqrt c + 2 sqrt c sqrt 5

you should know that
\[ \sqrt{a} \cdot \sqrt{b} = \sqrt{a\cdot b} \]
That rule means you can combine sqrt(c)*sqrt(5)

Answer 5

ok

Answer 6

i was thinking that the answer was A and still thinking because of what u showed

Answer 7

ok

Answer 8

I thought A was B. But A is not correct.

the answer is
3sqrt c + 2 sqrt c sqrt 5
or a simplified version of this

Answer 9

ok so D??

Answer 10

rewrite
\[ 3\sqrt c + 2 \sqrt c \sqrt 5\]
by putting the c and 5 inside the same sqrt

Answer 11

ok

Answer 12

do you have time to help me with two more?

Answer 13

first, did you finish this one?
put the c and 5 inside the same sqrt
\[3\sqrt c + 2 \sqrt c \sqrt 5\]

Answer 14

you can do that only for the 2nd term.

Answer 15

3 sqrt c + 2 sqrt 5c

Answer 16

ok, that should match one of your choices

Answer 17

C

Answer 18

so to do this, you distributed and then you combined two sq rt's

Answer 19

please post your other question separately

Answer 20

ok
