The integral expression for area will be

#A = int_1^6 1/x + ln(x^3)/xdx#

#A = int_1^6 1/x + (3lnx)/x dx#

We now let #u = lnx#. Then #du = 1/xdx#.

#A = [ln|x|]_1^6 + [3/2 *u^2]_(ln1)^ln(6)#

#A = ln(6) + 3/2ln^2(6) ~~6.607#

Use a graphing calculator's int function to determine the value. It should confirm this value.

Hopefully this helps!
