Question about Texas Instruments TI-30XA Calculator

I assume you want 40 raised to the one-third power?

Three simple ways.

Raise 40 to the one-third power: Press 4 0 y^x ( 1 / 3 ) =

or

Take the cube root of 40: Press 4 0 2nd cube-root = (the cube-root is the shifted function of the 0 key)

or

Take the third root of 40: Press 4 0 2nd xth-root 3 = (the xth-root is the shifted function of the y^x key, located just above the divide key)

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents

Division with the same base - subtract the exponents

Exponent to an exponent - multiply the exponents

Negative exponent - 1 over the same number to the positive exponent

Zero exponent - anything to the exponent 0 is 1

Good luck,

Paul

I don't have this calculator, but let's give this a shot and see if it gives us the correct answer.

Let's try 10 to the exponent -2. The rule for negative exponents is to put 1 on the top and the term with a positive exponent on the bottom. In this case, it would be 1 on the top and 10 to the exponent 2 on the bottom, or 1 / 100 or 0.01.

In the calculator, enter 10, hit the x to the power of y key, left bracket (, the negative key (-), 2, the right bracket ), and finally the = key. You might not have to enter the left and right brackets, but I like to enter them to understand what I enter in brackets is the exponent.

Let me know if it works and if you have any other questions.

Good luck.

You probably want to calculate the numerical value of some mathematical expression with numbers raised to negative exponents.

Just enter the expression as you would with positive exponents Except that before entering the value of an exponent**press the change sign key, marked (-), or +/- or (+/-)**. Do not confuse the change sign with the usual minus sign, which is usually displayed bigger then the change sign. Make sure that the (-) is displayed before the value of the exponent. Use parentheses if necessary.

In two parts. 40^77 is a 124-digit number, too large for the calculator to handle. But you can calculate it by separating it into (4^77)*(10^77).

Calculating 4^77 gives about 2.28*10^46. 10^77 is just that, 10^77. To multiply the two together, simply add the exponents to get 2.28*10^123.

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.

â€¢ Press [7] [y^x] [2] [+/-] [=].

â€¢ The calculator will display: 0.20408163.

2) 1*10^-3.

â€¢ Press [1] [EE] [3] [+/-] [=].

â€¢ The calculator will display: 0.001

Use the ^ key, located above and left of the 7 key. For example, to calculate 2 raised to the 120 power, press 2 ^ 1 2 0 =

Depending on your version of the TI-30, you will either find a button with a y to the exponent of x or a button that is the carot (^) sign. you would type (1.0075)^(-240), where ^ is the appropriate button (y^x or just ^).

To enter decimal exponents, use the x10^x key below the 3, followed by the exponent. For example, to enter one million, press 1 x x10^x 6 and see 1000000 (actually, the leading one is optional: if you press x10^x without a value, the calculator will supply a 1).

To raise a value to a number, use the x^ key above the sin, followed by the exponent. For example, to calculate 2^3, press 2 x^ 3 = and see 8.

Uh yes it will allow you to enter a negative exponent.... press the numbers you want then hit EXP button, then hit the +/- button and then the exponent. 60 % of the time, it works...... everytime.

The calculator has several decimal display formats: FIX, SCI, NORM and ENG.

Here are examples of calculations with different formats and how to set them.

It may be a good idea for a user to get accustomed to the scientific display format, because it is the one most calculators adopt when the result to be displayed is too large or too small--when there are not enough places on the screen to display the result.

To help you with the power of 10 notation

1 billion =1000 000 000 =1 E 09 (9 zeros after 1 >> exponent 9)

1 million=1 000 000 = 1 E 06 (6 zeros after 1 >> exponent 6

1 thousand= 1000 =1 E03 (3 zeros after 1 >> exponent 3)

One= 1 = 1 E0

One tenth = 1/10 =0.1: the 1 is ONE position after the decimal mark>> exponent -01

One hundredth =1/100 =0.01 the 1 occupies the 2ND position to the right of the decimal point, exponent -02

etc.

1/1000 =0.001 = 1E-03

1/10000=0.0001=1E-04 (1 in 4th position to the right of decimal mark)

1/1000000=0.000001 = 1E-06 (1 in 6th position to the right of decimal mark)

1E-09 =0.000000001 : the 1 is in the 9th position to the right of decimal mark.
