If you mean 3 raised to the power 375, sequence is

3
y to the power x (under OFF key)
375
=

Answer is "error" because the result exceeds the 9.9999.... times 10 to the power 99 limit of the TI-30XA

3 to the power 209 is about as far as you can go....

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

What is the answer to to this (x^5)^3(x^3)^4


We have to follow BEDMAS, the order of operations, where brackets are first, then exponents, followed by division and multiplication, and finally addition and subtraction.

Also, we have to use the exponent law of an exponent to an exponent, we multiply the exponents with the same base.

If we forget this, we can always do it the long way.

(x^5)^3 = (x^5)(x^5)(x^5) = x^15

Similarly, (x^3)^4= (x^3)(x^3)(x^3)(x^3) = x ^12

Now that we have done the exponents, we can multiply x^15 by x^12 and get x^27.

Good luck.

How do i enter an exponent on the


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 [=]

How do i enter an exponent for ti-30xiis


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.

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).

Which exponent function?
To enter an exponent of ten, use 2nd [EE].
To raise ten to an exponent, use 2nd [10^x].
To raise e to an exponent, use 2nd [e^x].
To raise an arbitrary number to an exponent, use ^.

Where is the exponent key on Casio fx-115es calculator?


To raise 10 to an exponent, use the 10^x function (SHIFT log). To raise e to an exponent, use the e^x function (SHIFT ln). To raise an arbitrary value to an exponent, use x^y (just above the sin key). To enter an exponent of ten, use the x10^x key to the right of the decimal point.

Exponent Sign


To write 50 exponent in math mode, type your number then hit the key that has (x with the solid white exponent key). It's between the (x squared key) and the (log key) then you can enter the number 50 for your exponent. You can also hit the (x squared key) delete the 2 exponent and type in the exponent you want.

Entering a problem


Hi Loringh,
see, high exponents are +ve powers, while low exponents are -ve powers.
e.g. for 1200000=1.2X10^6=1.2E+6 (high exponents)
for 0.0000000012=1.2X10^-9=1.2E-9 (low exponents)
I think so easy ?

Thanks
