Easy, PEDMAS

E.G.: 2^6 3 without parenthesis might register as 2^9, but (2^6) 3 is completly different.

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

It depends on the base of the power function.

**For exponential function** use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.

For a**general power**, type in the base (number), then press the [Y^x] key followed by the exponent.

For a**power of 10,** use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]

**1 . 6 [Exp] +/- 19 [=]**

Exponents of 10 are entered by pressing [2nd][X^-1] (EE).

For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

Hi there,

Type in your base and then press the button that says y with an x as an exponent (last row of the small buttons, second from the left). and then type in your exponent.

The base is -2x and the exponent is 5.

To enter exponents of an arbitrary base, use the key that is marked [Y^x]

To enter exponent of 10 press the [EE] key. In scientific notation display, the exponent of the power of 10 is displayed to the right of the mantissa.

Standard it says x^y or x with y superscripted. Insert the base, press that button, insert the exponent, press =.

Hello,

There is a rule of Algebra, that says

**(a^m)[x] (a^n) = a^(m+n) **

a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.

If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.

**If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10. **

I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as

2^7 + (5.5^3) - (1/3)^4

Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied

For the exemple above

2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543

For the cube of 5.5 you can use the key combination [2nd][X^3]

Hope it helps.

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.
