# Exponents Hi, I am having trouble finding in the instruction manual how to input exponents; more accurately negative exponents. If you would explain how, it would be greatly appreciated. Mary

I need to know how to do any number to a power.

No, not for someone new at statistics.

The Xy button, 10 Xy 2 = 100 (10 x 10)

to do a neg exp you have two options, one use brackets if calculator has them.....

10 Xy (-2) = 0.01

or two inverse your number, ie: make 10 into 1/10th, use fraction entry on calculator.

1/10 Xy 2 = 10 Xy (-2) = 0.01

sorry the Xy key changed to the ^ key on later models

• Mikey1963 Jun 03, 2008

It seems you don't even need the brackets with the newer calculators. I have an older fx-85v my daughter has a newer fx-85ms which is very similar to the fx-300ms.

to enter negative powers(exponents) just enter as is:

10 ^ -2 = 0.01

### What is most common power problem?

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

### How to solve an equation with negative exponent

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.

### How to use it for exponents?

To enter exponents (1, 2, 3, -3..) use the general power key marked with Y^x or X^y or ^. Enter the base press the general power key then the exponent. If exponent is negative try enclosing it in parentheses. use the change sign key (-) to enter the negative sign before the exponent.
To enter power of 10, you can use the shortcut key marked Exp (the 10 must not appear when the Exp is used to enter exponents for power of 10).

### Write with positive exponents

To rewrite an expression with positive exponents, you must use the identities
1/a^n=a^(-n) and 1/a^(-n)=a^n
Example: a^(-3)=1/(a^3)
1/(a^(-4))=a^(-(-4))=a^4
To convert a whole expression, you scan it for negative exponents and start changing them one a time, until you get only positive exponents.

Depending on the expresiion you are dealing with you may have to use other rules, such as (a^n)^m= a^(n*m)

### How do I use a negative exponent when working working with natural exponential functions, on this calculator?

The same way you'd work with positive exponents. The only difference is that a negative exponent has a negative sign, entered with the (-) key just to the right of the decimal point.

The (-) is used to enter negative numbers, not just exponents. The - key is used to subract one value from another.

### Please explain which buttons to push on TI-36x solar calculator to find the pKa of benzoic acid. the Ka for benzoic acid is 6.5 X 10 to the -5th ? (Sorry I don't know how to type the exponents for you)

You need the [EE] key to enter powers of 10 exponents.
You need the change sign key [+/-] key.
You need the [LOG] key.

pKa: 6.5 [EE] [+/-] 5 [LOG] [+/-]
There are two change sign: The first (either before or after the exponent 5), the last is entered after you press the log key , so as to negate (make negative if result is positive, and make positive is result is negative) the value.
The result should be 4.1870866 or 4.19

### Negative exponents? .825/(10^(-3)) ? Not sure how to get it to do the negative exponent.

You entered it correctly. Although you can leave out the parentheses if you want. The calculator will do exponents before it does multiplication or division just like it does multiplication and division before it does addition and subtraction. It has a built in order for hierarchy of operations. You only need to use parentheses if you want to do something that is different from this order. FYI, dividing by a negative exponent is the same as multiplying by a positive exponent. You could enter it in either way. .825/10^-3 = .825*10^3 = 825. I hope this helps you out.

### 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
