As far as I know, antilog is just exponentiation with a base of e, where e is the constant 2.71828 ... The TI-30XA has an operation marked as e^, which is 2ND-LN, using the "second function" key, and that's your button for antilog. So you would just key in -3.343 (using the +- key to get a negative number, rather than the - key for subtraction) and then antilog to get your answer. If what you're after is general exponentiation with any base, you need to use the y^x key, which is a y with a superscript x.

1. 15 - x over 4 = -8 (15 - x) / 4 = -8 (15 - x) = -32 -(15 - x) = 32 x = 47 2. what happens if the 8 were a positive? 15 - x over 4 = 8? (15 - x) / 4 = 8 15 - x = 32 x = 15 -32 = -17 3. also dealing with percents! what would the percent increase be? $50.00 is the Original price $80.00 is the new price Percent increase = 60 4. Find the discount price 49.99 discount 25% 37.49
