How do I do exponents on this calculator?


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

How do I enter (5^2) or (5 with an exponent of 2) on the TI-30XA?


Most simple way is: 5 [x²] [=]

How do i divide by powers of 10 in my TI-30XA calculator?


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.

Where is the exponent key on a ti-30xa


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.

Where is the exponent button on the ti-30xa


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. If you're asking about antilogarithms, use the second shift of the appropriate logarithm key on the top row.

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.
Thank you for using FixYa

1.19x10-4=?


You can download the guidebook for this calculator from TI here.

From page 16:
To enter a number in scientific notation:
1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)
2) Press the EE key.
3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.
