SOURCE: Negative Exponent

1. Type in your base number

2. Press the EE button

3. Key in your exponent number.

4. Press the button on the bottom right hand side of the calculator that has both the positive and negative sign on it.

5. Press equals button.

SOURCE: How do I calculate compound interest?

Hello,

You enter that as follows**3500[x] (1.064)[Y to the x]3.5** [=] . Note that [x] is the multiplication sign.

Hope it helps.

SOURCE: decimals in the exponents for TI-30Xa

Hi,

You have a key labeled [Y to the x], use it for all the powers or roots that do not have a dedicated key or key sequence. Let the key be [^]

Ex: 13.675 to the power 1.33 is entered as 13.675 [^] (1.33) [=].

The result is 32.41778634

Ex: (-64)[^](2/3) [=] gives 16 as result. The (-) is the change sign key

Ex: (2.87655)^(-6.778) is entered as 2.87655 [^] ( (-) 6.778 ) [=] 0.0007758

The (-) is the change sign (or the negative of), not the regular minus. When you have a negative exponent or a complicated exponent, it is safer to enclose the whole exponent inside parentheses.

Hope it helps.

Use the key marked "EE" (for Enter Exponent). For example, to enter 1.2 times 10 to the 17th, press 1 . 2 EE 1 7

The TI-30Xa will only handle fractions with denominators less than or equal to 999. .003 is 3/1000 in simplest terms, with a denominator larger than 999. Thus the calculator cannot display it as a fraction.

Use the +- key to the right of the decimal point to enter negative values and to change the sign of an existing value. For your sample:

2 EE +- 3 LOG +- =

2 EE +- 3 LOG +- =

Nov 15, 2010 | Texas Instruments TI-30XA Calculator

Use the EE key, just as for positive exponents. Just make sure you use the +- key (next to the decimal point key) to enter negative values, not the - key which is for subtraction.

6 . 2 EE +- 8 LOG +- =

EE is the Enter Exponent key, just above the 7 key. +- is the Change Sign key, to the right of the decimal point key.

EE is the Enter Exponent key, just above the 7 key. +- is the Change Sign key, to the right of the decimal point key.

To enter powers of 10 you use the [EE] key.

EX: 1.07 x10^(38) type in 1.07[EE]38 [=]

EX: 1.07 x10^(38) type in 1.07[EE]38 [=]

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.

If you're asking about entering powers of ten, use the EE (enter exponent) key just above the 7. If you're asking about exponentiation, use the y^x key just above the divide.

Hello,

I dont think you got a lemon.

You acn always enter the powers of 10 as 10, [y^x], but is is less efficient than the EE key

This EE representation is a shortcut.

If you want 10 to the 5th power you just enter [2nd] [EE] 5 and the calculator displays 100000. Of course if you need any other number multiplying the power of ten you enter the following e.g. 2.677[x][2nd][EE]5.

You will not get any error with a positive exponent. But if your exponent is negative you should use the change signe key to the left of ENTER and symbolized by (-)

To avoid all errors I would use parentheses to enclose my exponent.

Here is how to explain the seemingly erroneous result

10 [EE] 5 ) (-) is interpreted by your calculator as 10x(10^(-5)) which evaluates correctly to 0.0001 because [EE] by itself stands for 10^ .

Hope it clarifies this point for you.

By the way some new calculators (Casio) don't have this EE key. Instead you find a key labeled x10^X .

Hope it helps
