Good day sir
Can you please make a video on how to use logs

[@MzilikaziMaloba]

for the geometric formula isnt it supposed to be : a(1 - r^n) / 1-r ????? but instead its a(r^n - 1) / r-1

[@feetstrighter9hunned562]

How do you type log1/2(3/128) on a calculator

[@dineokgatla172]

I also can't get that @kevin please help

[@Chichi_Hills221]

Isn't it supposed to be divide by 126 and not 128?

5.42- 2 +1 is 4,42 not 6,42

[@salmaan6439]

wrong.
we move the -2 and +1 over and then they change signs to +2 - 1.
