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.
inverse log of -2.6

One is the inverse of the other, just like the arc-sine is the inverse of the sine, or division is the inverse of multiplication.
b^x In general the log and the exponential are inverses.
An exponential function is of the form y = a^x, where a is a constant. The inverse of this is x = a^y --> y = ln(x)/ln(a), where ln() means the natural log.
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.)
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.
The TI-30X is a Scientific Calculator.It has features close to programmable,but not actually so.
inverse log of -2.6
it simplifys on its own.

inverse log of 2= 1/(log{10}2)= 1/(log2)=1/0.3010299=3.3219. hence answer is 3.3219
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.
you cant. you have to buy one because they are such good calculators.
You can use any standard scientific calculator, such as the TI-30x.
Yes, the Texas Instruments TI-30X IIS, released in 2003, is a scientific calculator. It is an updated version of the TI-30 scientific calculator from 1976, which sold for $25.
