Using logarithms. For example, if A ^ X = 2; then X = logA(2);

This calculator only works in base-10 logarithms or natural logarithms, you should use the base conversion formula.

logA(X) = logC(X) / logC(A).

Good luck!

The following examples will demonstrate how to
convert decimals into fractions using the TI-30Xa and TI-30Xa Solar.
Please be aware that TI-30Xa Solar School Edition calculators do not
have this functionality.

**Example**: Convert .25 to 1/4

- Input .25, press [2nd][<--] (says F<>D above it).

**** F<>D means fraction to decimal, decimal to fraction. **

**Example**: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

**Example**: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

- Input 1.38, press [2nd][<--].

- Input 9.75, press [2nd]{<--].

Because this calculator does not allow you to enter formulas, you have to alter the formula a bit.

Instead of entering 3.55*10^24, enter (10^24)*3.55

Note: 10^24 is 10 to the 24.

Here is the procedure:

1) find 10^24. Do this by typing 10, pressing the yx button (which is right above the divide button), and then typing 24. Press the '=' button.

2) multiple the result by 3.55. Press the '=' button.

You now have the answer.

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

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....

Display has gone....you will have to buy a new calculator, fortunately the TI-30XA is only $10-$15!!
