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

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)

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

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

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

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

you can do that only for the 2nd term.

ok, that should match one of your choices

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