The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.

### Calculating chemistry 1 scientific equation divided into another?

Use the rules for exponents and you will calculate it by hand
(1*10^-14)/(5*10^-12)=(1/5)*10^(-14+12)= 0.2*10^-2=2*10-3
To enter powers of 10 use the short-cut key [EE]
For example to enter 6.02*10^23 type in 6.02* [EE] 23. When you use the EE key, the base (10) should not appear.

### Change log base

The TI-30XA calculates logarithms to base e and base 10. You can calculate the log of x to any base b by calculating the logarithm of x and dividing it by the logarithm of b: log(x)/log(b) or ln(x)/ln(b).

### How do i use the TI-30XA for algebra

Well it depends on what you are wanting to do.
1. Graphing- get a graphing calculator!
2. logistics- for log base 10, just divide the number by 10.
3. ln- divide the # by the number e (roughly 2.72)
4. sine, cosine, and tangent- there should be a "SIN", "COS", and "TAN" button, if not the ratio for each, respectivly is opposite/hypotnenuse, adjacent/hypoteneuse, and opposite/adjacent. (The opp/adj being side opp or adj of angle you are doing)

### How to do problem (8.99 x 10 to the negative 8) divided by .738 on the Ti-30xa

### How to make this operation in my texas instruments TI-30XA 3.55*10(to the 24)

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.
