Best ResponseYou've already chosen the best response.03sqrt(28)=3sqrt(4*7)=3sqrt((2^2)*7)=3sqrt(2^2)sqrt(7)=3*2*sqrt7=6sqrt7

Best ResponseYou've already chosen the best response.0How would you do the square root of this problem: 3 square root of 54. The answer is supposed to be 9 square root of 6.

Best ResponseYou've already chosen the best response.0can you write 54 into product of prime numbers (1,2,3,5,7,11,....) for me?

Best ResponseYou've already chosen the best response.0ok, there you have 54=2x3x3x3. there is a rule like this: sqrt(a^2)=a, a>0 so you have 54=2x3x3^2 sqrt54=sqrt(2x3x3^2)=sqrt(2x3) x sqrt(3^2) you do the rest for me? the thing here is you need to understand how it work, then you can do any problem

Best ResponseYou've already chosen the best response.0. \[3\sqrt{54}=3\sqrt{2*3*3^{2}}=3\sqrt{6}\sqrt{3^{2}}=3*3*\sqrt{6}=9\sqrt{6}\]

Best ResponseYou've already chosen the best response.0I understand how you factored it down but how do you get the answer of 9 square root of 6?

Best ResponseYou've already chosen the best response.0√(3^2)=3, you understand this right? so√(54)=√(2*3*3^3)=√(6*3^3)=(√6)*(√3^3)=(√6)*3 then 3*√(54)=3*(√6)*3=3*3*(√6)=9√6 clear?
