Casio FX-300MS Calculator Questions & Answers
How do you solve radicals on the casio fx-300ms
To calculate radicals use the square root key. For higher index roots use [SHIFT][X^y]. You need to enter the index before pressing the key. Or use the general power key but with exponent (1/n) where n is the index of the root.
Floating point number into binary in fx-991MS
I checked in the manual and found that this calculator does not support Base-N calculations. On the FX-991ES Plus, which has a Base-N mode, fractions , exponents, and other floating points are not supported. The non-integer part is chopped off.
Logarithm
The Casio FX-300MS does not provide base 2 logarithms as a single key operation. However, you can use the natural logarithm (ln, base e = 2.7182818...) and the formula
log2 ( x ) = ln( x ) / ln( 2 )
To calculate the base 2 logarithm of 16, key in
[ln] 16 [/] [ln] 2 [=]
and get displayed the correct answer 4.
The same simple formula also works for any other base, and actually for any other logarithms provided by your calculator. The FX-300MS also provides a logarithm to base 10 (lg). You could also
type
[lg] 16 [/] [lg] 2 [=] to get the solution to the problem above, or
[lg] 25 [/] [lg] 5 [=] to get the base 5 logarithm of 25.
How do you work out 2 2/9+3 3/4
Convert to common terms, add, then simplify if necessary.
2 2/9 is 2 8/36 or 80/36. 3 3/4 is 3 27/36 or 135/36. Adding gives 215/36 or 5 35/36.
