Integral e^x from ln 5 to ln 9

for best answer?

integral of e^x is e^x
now the upper limit and the lower limits are ln9 and ln5. So you will have to put the value of the limits instead of x
therefore, [e^(ln9) - e^(ln5)]
=> 9-5 = 4

since e^(ln9) =9 and e^(ln5)=5 because the base of ln is e

∫ e^x [ln5, ln9]
e^x [ln5, ln9]

e^(ln9) - e^ln(5)
9 - 5
4
