Best ResponseYou've already chosen the best response.0Use distributive property a(b+c)+ab+ac Here a=sqrtc b=3 c=2sqrt5 Does that help? @Solmyr

Best ResponseYou've already chosen the best response.1Sqrt c(3 + 2 sqrt 5) + sqrt c(3) + sqrt c(2 sqrt 5)

Best ResponseYou've already chosen the best response.1it 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)

Best ResponseYou've already chosen the best response.1i was thinking that the answer was A and still thinking because of what u showed

phi

Best ResponseYou've already chosen the best response.1I 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

Best ResponseYou've already chosen the best response.1rewrite \[ 3\sqrt c + 2 \sqrt c \sqrt 5\] by putting the c and 5 inside the same sqrt

Best ResponseYou've already chosen the best response.1do you have time to help me with two more?

phi

Best ResponseYou've already chosen the best response.1first, did you finish this one? put the c and 5 inside the same sqrt \[3\sqrt c + 2 \sqrt c \sqrt 5\]

Best ResponseYou've already chosen the best response.1ok, that should match one of your choices

phi
