    X=4.35

    Step-by-step explanation:

    Let's start solving

    3 (x-3) ^2-162=0

    Add 162 to both sides

    3 (x-3) ^2=162

    Square root both sides

    √3 (x-3) = √162

    1.73 (x-3) = 12.727

    Open the bracket

    1.73x-5.19=12.727

    Add 5.19 to both sides

    1.73x=7.5327

    Divide both sides by 1.73

    x=4.35
