Question

(5x-3)^2/3 =9 please help

Answer 1

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

Answer 2

THANK YOU SO MUCH

Answer 3

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

5x = 27 +3
x = 30/5
x=6
case 2:
5x -3 = - 3^3
5x = -27 +3
x = -25/5
x = -5
