Best ResponseYou've already chosen the best response.0if I understand the problem the approach is: multiply both sides by 3: (x1)^2 39=9 add 39 to both sides: (x1)^2 = 48 x=2* (3)^1/2 +1

Best ResponseYou've already chosen the best response.0\[(x1)^{2/3}13=3\] x4 = √(9x) \[\sqrt{x+6}\sqrt{x5}=1\]

Best ResponseYou've already chosen the best response.0(x−1)^(2/3) = 16 now raise both sides to the 3/2 power x1 = 16^(3/2) x1 = 64 so x = 65

Best ResponseYou've already chosen the best response.0To get rid of a square root raise both sides to the 2nd power. (√x is the same as x^(1/2)

Best ResponseYou've already chosen the best response.0(x4)=√9x (x4)^2 = 9x now do you know how to raise x4 to the second power?

Best ResponseYou've already chosen the best response.0i gotta do 4(4) so its gonna be x^2+16=9x?

Best ResponseYou've already chosen the best response.0almost but you also will have a 8x on the left

Best ResponseYou've already chosen the best response.0(x4)^2 = (x4)(x4) and you have to distribute x^2  4x  4x + 16 x^2  8x + 16 = 9x

Best ResponseYou've already chosen the best response.0do i bring the 9x to the lefts side, or the 8x to the right side

anonymous

Best ResponseYou've already chosen the best response.0I would move the 9x to the left side by subtracting it.

Best ResponseYou've already chosen the best response.0So you will end up with x^2  17x + 16 = 0 Now do you know the quadratic formula?

Best ResponseYou've already chosen the best response.0ok so far i got 17+*225/32*

anonymous

Best ResponseYou've already chosen the best response.0(17+√225)/2 √225 = 15 (17+15)/2 = 16 (1715)/2 = 1 The answer is x = 1 and 16

Best ResponseYou've already chosen the best response.0how did u get the 2, on the first line

anonymous

Best ResponseYou've already chosen the best response.0in the denominator of the quadratic formula you have 2a and in the problem a = 1 (the number in front of the x^2 term)
