wow. thanks. thank you so much!=)

Answer 9

No worries :)

Answer 10

wait. howcome we just divided it?

Answer 11

because we are integrating so the rule is given by

\[\int ae^{kx} dx = \frac{a}{k}e^{kx}\] where a and k are constants

Answer 12

if you derive the answer you will get the original equation. <--- you can use this fact to check your answer

Answer 13
