4 The calculator must be in MATH mode. Press the log button as described in the manualthen 2 then the right arrow and the number you need then = Easy when you know how.. the manuals with these are hopeless.

3 ooh! my friend,..you can't find directly this using fx-991MS. So you can follow this, 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) thank you...
