    basically what you do to one side you do to the other

    so after you have ln x = 4

    you see ln x on one side you need the opposite function to ln x that is e ^x

    if you take e^{ln x} you get x

    so thats how all those got the answer x = e^4

    3 ln x = 12 ⇒

    ln x³ = 12 ⇒

    e¹² = x³

    x³ = 162754.79141900392080800520489849

    x = 54.598150033144239078110261202861.................ANS (This equals e⁴)
