in a scientific calculator there actually 2 buttons are for Logarithm calculation.

1. "

2. "

now to calculate log base 2, you can use any of these two, but whichever, you gonna need to convert it into base 2.

If you to calculate

log8 base 2 is 3. using calculator is should be log8 base 10 / log2 .

thank you :)

1. "

**log**" button: is to calculate**log base 10**(known as**Common Logarithm**)2. "

**ln**" button : is to calculate**log base e**(known as**Natural Logarithm**)now to calculate log base 2, you can use any of these two, but whichever, you gonna need to convert it into base 2.

**You can do this by**__dividing__your result by the "log" or "ln" of base 2.**:**__e.g__If you to calculate

**log(x) base 2**, then calculate**log(x) base 10 then divide it by log2**or to calculate**ln(x) base 2**,**do it with base 10 then divide it by ln2**.__example calculation:__log8 base 2 is 3. using calculator is should be log8 base 10 / log2 .

thank you :)
