Best ResponseYou've already chosen the best response.15 srqt 3 (2 sqrt3 sqrt 3 + 6 sqrt 3 sqrt 19)??

Best ResponseYou've already chosen the best response.1in letters: A * (B+C) = A*B + A*C take the "stuff" in front (in this case 3 sqrt3 ) and multiply it times each thing inside

Best ResponseYou've already chosen the best response.15 sqrt 3 (2 sqrt 3 + 6 sqrt 19) you have two terms inside the parens: 2 sqrt3 and 6 sqrt19 you multiply each term by 5 sqrt3 for the first term just write it like this 5*sqrt3 * 2 * sqrt3 ( I put in * to show the multiplication, but in algebra you normally don't show the multiplication sign, and just know it is there.) however, put the numbers first (when you multiply you can switch the order) 5*2 * sqrt3 * sqrt3 you know what 5*2 is , right ? do you know what sqrt3 * sqrt3 is ? and do the same thing for the 2nd term: 6 sqrt19

Best ResponseYou've already chosen the best response.1ok so 10 sqrt 6 and 5 * sqrt 3 * 6 * sqrt 19 giving me 5 * 6 and sqrt 3 * sqrt 19 then giving me 30 sqrt 57 Answer = 10 sqrt 6 + 30 sqrt 57

Best ResponseYou've already chosen the best response.1giving me 5 * 6 and sqrt 3 * sqrt 19 then giving me 30 sqrt 57 that part is correct. do the first part again 5*2 * sqrt3 * sqrt3

Best ResponseYou've already chosen the best response.1yes. but what is the square root of 9 ?

phi

Best ResponseYou've already chosen the best response.1yes so 10*sqrt(9) is 10*3 or 30

Best ResponseYou've already chosen the best response.1what is the first term? (5*2 * sqrt3 * sqrt3) + (5 * sqrt 3 * 6 * sqrt 19)

Best ResponseYou've already chosen the best response.1the first term is 10 sqrt 9 simplified its 10 sqrt 3

Best ResponseYou've already chosen the best response.1next term is 30 sqrt 57

Best ResponseYou've already chosen the best response.1the first term is 10 sqrt 9 simplified its 10 sqrt 3 < no. sqrt(9) is 3 square root of 9 is 3 because 3*3=9

phi

Best ResponseYou've already chosen the best response.1so if you see sqrt(3*3) you know that is 3

phi

Best ResponseYou've already chosen the best response.1so, the answer for this question is 10 sqrt 9 simplified its 10 *3 =30 for the first term.

Best ResponseYou've already chosen the best response.1yes, also I noticed a typo in my rules: sqrt(x) * sqrt(x) = x is the rule or sqrt( x*x) = x or sqrt(x^2) = x < (it is x, not 2 like I had) those are 3 different ways of saying the same thing. try to remember this rule.
