Question about Texas Instruments TI-30XA Calculator
There is not a carat button ^ or x to y or y to x button that i can find.
The y^x button is located along the right edge of the keyboard, just above the divide key.

Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10

SOURCE: cant get M2 off of my TI-30XA calculator
Remove the six screws on the back cover. After the batteries are installed you need to reset the board. There is a little reset area that needs to be shorted to get the calculator back to normal. Look closely at the circuit board- You'll see a little circle next to the word reset. Its near the middle of the board. Wet your finger- press it on the circle. It should short. Blow it dry with your breath. It should work...

SOURCE: Inputing scientific notation into my calculator
Hello,
1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19
Hope it helps

SOURCE: how do I reset the calculator after installing new
[OFF] ON/C] clears display, errors, all pending operations, constant calculations K, and STAT, but not M1, M2,and M3. Sets DEG angle units, floating-decimal format.
To clear memory M1 : Store 0 in 1
0 [STO] 1 clears M1
0[STO] 2 clears m2
0 [STO] 3 clears M2
