You can't convert milliwatts to decibels, but you can convert them to dBm or dBw. dBm = 10 log (milliwatts) dBw = -30 + 10 log (milliwatts)
log (3 x 66) = log 3 + log 66
nun yo business
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
To get the inverse log function, press 2ND and then choose 10x. (Above LOG.) To get the inverse of a natural log function, press 2ND and then choose ex. (Above LN.)
Use the LOG function. =LOG(n,b) n = Number b = Base =LOG(2,10) = 0.30103
It is because the logarithm function is strictly monotonic.
pH is -log[H+] and can be found using pH meter.
The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
On the TI-30x model there is no INV button. You have to use the 10^x function. To do this press the button labeled "2nd" and then the button labeled LOG. Above the LOG button you should see the 10x function which is the same for INV.
