This is the best solution:
It can only be done by changing the base of the logarithm.
The change of base of logB(a) can be found by the division:
logB(a)= [log10(a) / log10(B)]
Note: The change can be to any base but I've simply used base 10 as it's most commonly used.
so it your case you'd find:
log2(a)= [log10(a) / log10(2)].

SOURCE: where is the math button on the casio fx-9750G11
It is a calculator and prqactically every button is a MATH button. It
depends on what MATH you intend to do. Put the calculator in Run/Mat
screen then press the OPTN key. You will see several tabs. Press the
function key under a TAB and explore what is offered. Go through all the
keys (F6 also) and see what the new tabs do.
In general it is most helpful to read the manual that shipped with the calculator.
