Here is an easy one for someone to nail.
Need to solve: In x = -79.93
I know x = e^-76.93
but how do i get to the answer 4.93 x 10^-34
I have an "In" button on my calc., the shift function of this is "e^x".
Please help.
I think the answer your teacher provided you with is false... I've tried it out and it doesn't yield his answer
Are you sure you copied it well ?
(%i1) %e^(-79.93);
(%o1) 1.9357178794122214*10^-35
(%i2) 10^(-79.93);
(%o2) 1.1748975549394918*10^-80
(%i3) 10^(-76.93);
(%o3) 1.1748975549394913*10^-77
(%i4) %e^(-76.93);
(%o4) 3.8879932939808711*10^-34
