    I took the natural logarithm of both sides and got x-1=1. From here, the solution is x=2.

    Very nice explanation

    If logₐb=x, then, by definition of log, aˣ=b. Substituting for x we get a^(logₐb)=b. Substituting for b we get another basic (but more familiar) identity logₐ(aˣ)=x.

    Take Naperian logarithm:
    x-1=[1/ln(x)]ln(x)
    =1 --> x=2

    I like the second substitution method.
    ‘E’ to the ‘t’ equals ex-tra terrestrial. 😂😂

    x=2
    e^x- 1 = x^ 1/log e x
    e^x/e = x^ log x e (as 1/log a b = log b a /1)
    e^x/e = e ( a^log a B = B)
    e^x = e* e ( MULTIPLY BOTH SIDES BY e)
    e^x = e^2
    x = 2 Answer (relating the base)

    If we raise both sides to the power ln(x), the equation simplifies to x^x = x². While we get x = 2 as a solution, but also x = 1 which seems kind of correct? Are there any other solutions that may not necessarily be Real?
