Exponential Functions

Hi,

I am working on the exponential functions but the answers I am getting from my calculator does not seem to be matching with the book answers.

For example, 116.75e^.101(4) = 516.63. However, the answer in the book is 175. I dont understand what I am doing wrong.

The book is calculating $\displaystyle 116.75e^{.101 \cdot 4}$, and you're calculating $\displaystyle 116.75e^{.101} \cdot 4$...

atari,

in your calculator try entering it as this:

116.75e^(.101*4)



(Note that 175 is rounded to the nearest integer.)
Thanks from atari
