Find all the real-number roots of each equation. Give an exact expression for the root and also a calculator approximation rounded to three decimal places. (Enter your answers as comma-
separated lists.)
(a)
In(x11) = 11 In x
O Since In(x¹¹1) = 11 In x, the equation is true for all x ≥ 0.
Since In(x¹¹) = 11 In x, the equation is undefined for all x.
O Since In(x¹1) = 11 In x, the equation is undefined for all x > 0.
Since In(x¹1) = 11 In x, the equation is true for all x > 0..
Since In(x¹1) = 11 In x, the equation is true for all x.
(b)
x =
(In x) ¹1 = 11 In x
