You can put this solution on YOUR website! First do the calculation inside the parenthesis:
log_4(256)= 4 Now calculate log base 2 of 4:
log_2(4)= 2 This is your answer.
-----------------------------------------------
NOTE: the hand-held calculators I know only calculate natural logarithms (ln) and log base 10 (log).
To calculate a log with a different base you have to use the formula: .
Let's do one of yours, the one inside parenthesis: I used 3 decimals to get a more accurate answer.
Now follow this example and do log_2(4). Your result should be 2.
Once you get the hang of it it's really very easy.
