Casio fx-8200 AU - Logarithm(Logab), Logarithm(Log)

∏ Calculation Example
(x + 1) = 720
(Input/Output: MathI/MathO)
– [Func Analysis] > [Product(Π)]
1 1 5
(Input/Output: LineI/LineO)
– [Func Analysis] > [Product(Π)]
1 (,)1 (,)5
Logarithm(logab), Logarithm(log)
Use
(log) or – [Func Analysis] > [Logarithm(log)] to input log
a
b as
log (a, b). Base 10 is the initial default setting if you do not input anything
for a.
Example 1: log
10
1000 = log 1000 = 3
(log)1000
Example 2: log
2
16 = 4
(log)2 (,)16
The key (or – [Func Analysis] > [Logarithm(logab)]) also can be
used for input, but only while MathI/MathO or MathI/DecimalO is selected
for Input/Output on the SETTINGS menu. In this case, you must input a
value for the base.
Example 3: log
2
16 = 4
2 16
