While checking logarithmic curves on a calculator, a machine design student noted that a certain robotic arm was shaped like part of the graph of y = ln(2x^2/3). As a check, the student re-wrote the equation as y = (2ln x)/3 + ln 4 − ln(ln e²). Write a paragraph explaining 

(a) Whether the second equation is equivalent to the first, 

(b) If the graphs of the two equations are identical.
