in 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

5 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

ok 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

giving 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

5*2 = 10 sqrt 3 * sqrt 3 = sqrt 9 10 sqrt 9

phiBest ResponseYou've already chosen the best response.1
yes. but what is the square root of 9 ?
 one year ago

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

what is the first term? (5*2 * sqrt3 * sqrt3) + (5 * sqrt 3 * 6 * sqrt 19)
 one year ago

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

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

phiBest ResponseYou've already chosen the best response.1
the 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
 one year ago

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

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

yes, 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.
