to make your life easier raise both side to power of three. try to solve the rest on your own or continue reading (5x - 3)^2 = 9^3 (5x - 3)^2 = 3^6 //square root of both side 5x - 3 = \[\pm\] 3^3 case 1: 5x -3 = 3^3 5x = 9 +3 x = 12/5 case 2: 5x -3 = - 3^3 5x = -9 +3 x = -6/5

THANK YOU SO MUCH

\[(5x-3)^{2}/3=9\]\[(5x-3)^{2}=3(9)\]\[(5x-3)=\pm \sqrt{27}\]\[5x=3\pm \sqrt{27}\]\[x=(3\pm \sqrt{27})/5\]

vivki do you mean (5x - 3)^(2/3) = 9 or ((5x - 3)^2)/3 = 9

Just use equation
anonymous
  • anonymous
how do u do fraction exponent on here
anonymous
  • anonymous
Just hit the equation buton. Then look for the \[x^{a}\]
anonymous
  • anonymous
Type x and then the x^a button.
anonymous
  • anonymous
use brackets to show fraction and 4th button from tom shows you exponent
anonymous

\[solve (5x-3)_{3}^{2}=9\]

OK then Safdari's answer should be correct.
anonymous
  • anonymous
which answer?
anonymous
  • anonymous
x=12/5 and x=-6/5
anonymous
  • anonymous
i tried both and it still says incorrect idk y
anonymous
  • anonymous
I didn't really look at the arthmetic. Give me a moment to check it.
anonymous
  • anonymous
ok thank you so much for your time
anonymous
  • anonymous
OK, Safdari had the method correct, but didn't do the arithmetic correctly. The answers should be x=6 and x=-24/5
anonymous
  • anonymous
ok let me try
anonymous
  • anonymous
mayb my homework is looking for something else im not sure. but thanks alot for your efforts
anonymous
  • anonymous
marshall thanks for correcting, marshal is right but I think the right answer is case 1: 5x -3 = 3^3 5x = 27 +3 x = 30/5 x=6 case 2: 5x -3 = - 3^3 5x = -27 +3 x = -25/5 x = -5

  • anonymous
vicki try 6 and -5
anonymous
  • anonymous
:( no luck

i do have other math homework i need help on. know of anywhere online i can pay for help?
anonymous
  • anonymous
if I were you, I would just use MIT open course and learn them then I would do all homework myself. Send your homework here, maybe I can do something with it, this time. Trust me learning is more important, and asking some one to solve your assignment will not help you in future
