What you call the antilog is also known as as the power function. More specifically, the inverse of a decimal log is the function 10 to a power, (10^x) It shares the same physical key as the log function. If the calculator has a key marked [LOG] you have to press the [2nd or SHIFT] key followed by the [LOG] key to activate the anti-log.

For natural log (logarithms in base e) the antilog is the exponential function (e^x). It shares the same physical key as the [LN] function.

You can download the TI-30Xa guidebook from the manufacturer's web site at

The TI-30Xa replaced the TI-30X within a year. The only enhancement was the added Constant key.

The TI-30XII, introduced about five years later, is a significantly different calculator, incorporating, among other things, a two-line display.

### HOW DO I TYPE IN LOG BASE 3 OF 18 IN MY TI 30X

You can calculate the log to any base by using the relationship logb(x) = log(x)/log(b) = ln(x)/ln(b). In words, the base-b logarithm of x is the logarithm of x divided by the logarithm of b.

So, to calculate the log base 3 of 18, press
1 8 LOG / 3 LOG =
or
1 8 LN / 3 LN =
