How do I clear the ln in my solution?

Must solve for r


Step 1: 49 = r^4


Step 2: ln49 = 4lnr


Step 3: ln49/4 = lnr


Step 4: ????


Step 5: Profit!How do I clear the ln in my solution?
Taking logs doesn't really help here (if you want exact answer)


r = 卤 49^(1/4)


r = 卤 ((49)^(1/2))^1/2


r = 卤 鈭? (Two real solutions. I'm ignoring the complex solutions here)How do I clear the ln in my solution?
(ln49)/4 = lnr


.973 = lnr


e^.973 = e^lnr = r


2.6459 = r
