So I was working with this expression:
$1111 = 5 * 2^t$
after working it out until here
$2.346744/0.301029 = t$
I decided to use a calculator to know the value of $t$ just for fun. Using windows 10 calculator I got the value of $7.7957406097086991618747695404762$.
I was typing the exercises in Microsoft Word using the Design Equation functions and then under the Calculate option I hit the option that says: "Solve for t" and got this value instead: $t=782248100343$.
The lesson I was following on KhanAcademy ended up showing Sal using the ti-85 emulator which ended up with the result: $7.7957150065$.
So I am a little confused why so many different values?
I do understand that I only used 6 digits when performing the division which is not how Sal did it (he performed the division of logarithms directly) but In word and Microsoft Calculator I did have the same values so at least there the results should be exactly the same.
Any reasons why this might not be the case?
