Sorry, you can't. the TI-30XA limits exponents to +/-99.

Two keys can be used to enter negative exponents on the TI-30Xa scientific
calculator; the [y^x] key or the [EE] key. The [y^x] key is used for
all exponents while the [EE] key is used for scientific notation only.

The examples below will demonstrate how to use both keys:

1) Entering 7^-2.

• Press [7] [y^x] [2] [+/-] [=].

• The calculator will display: 0.20408163.

2) 1*10^-3.

• Press [1] [EE] [3] [+/-] [=].

• The calculator will display: 0.001

Most simple way is: 5 [x²] [=]

For arbitrary exponents, you can use 5 [*yx*] 2 [=].

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

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.

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

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.

Did you press 1 0 EE 2 to get 1000? That means 10*10^2 which is 1000.

ya, thanks. I figured it our.
