You need the change of base formula:

log base b of m is ln m / ln b

So- to find log base 2 of 8, simply find ln8/ln2

(from Wikipedia - the proof also follows if you want to go look it up)
While there are several useful identities, the most important for calculator use lets one find logarithms with bases other than those built into the calculator (usually loge and log10). To find a logarithm with base b, using any other base k:

How to calculate 0.3log(base 2)0.3 using fx-991ms calc


Your calculator knows only the decimal logarithms log or log_10 and the natural logarithms (ln or log in base e).
So you cannot compute directly the logarithms in any bases other than 10 and e.
A workaround consists in using the relation
log in base b of a number a (log_b (a))
log_b(a)= (log_10(a) ) / (log_10 (b))
or the relation
log_b(a)= ln(a)/ln(b)

log_2(0.3)=log(0.3)/log(2) where log is log in base 10
Similarly
log_2(0.3)=ln(0.3)/ln(2)
As to the multiplicative factor you had at the beginning of your expression, just multiply the value obtained by one on the formulas above (both formulas will give the same result) by 0.3

How to calculate ln using fx-991ms


Hello, There is a key for that, the one labeled [ln] for natural logarithm. For log in base 10 use the key [LOG] [LN] 10 [ENTER] gives 2.302585093. As you certainly know, you cannot take the logarithm of a negative number, nor of Zero.
Hope it helps.

How to calculate calculus problem by a scientific calculator fx-991ms


Hello,
If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

How to calculate log value in calculator with different base value


In any scientific calculator log2(n) can be  calculated with either ln or log function as follows
 
Log2(n)= ln(n) / ln(2)
 
Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers
