To ten to the power of three you must use the caret symbol. It is located above the division symbol on a Ti-83. It looks like this: ^

Meaning what, exactly?

If you want a decimal representation of an exact number, press the SD key to switch from exact to approximate (decimal). If you want to expand a decimal number in powers of 10, separate all the digits, multiply every digit by a power of 10 with exponent equal to its position as counted from the decimal mark -1. To the left of the decimal mark, the exponent is positive. To the right of the decimal mark, the exponent is negative. Sum everything

Example

345.678 =3*10^(3-1)+4*10^(2-1)+5*10^(1-1)+6*10(-1)+7*10^(-2)+8*10^(-3)

Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

Look for a key that may be marked as X to power y, or Y to power x or just a caret [^]. However to enter a power of 10 such as in the Avogadro Number 6.02*10^23, scientific calculators have a specific key marked EE (enter exponent?) on TI's or x10^x on Casios.

**When you use the EE key no 10 should appear: meaning to enter 6.02*10^23 you type in 6.02 followed by [EE] then 23. Press = to display the number**. Th e EE key is a shortcut for *10^

The numbers on binoculars in the form 00x00 are the power and the diameter of the objective (the main lens). A common one is 8x30, for small binoculars of 8 power and an objective 30mm in diameter.

10-30x60 is a bit more complicated. The diameter of the objective is 60mm, but the first numbers with the hyphen indicate a range of powers, from 10 to 30, because these binoculars have a zoom feature, giving variable power.

In my view, zoom on boinoculars is a gimmick. It isn't useful in practice, usually giving too much magnification to be useful at the high power end, and the complication it adds to the optics means that the image is not as good as with simpler binoculars of similar quality.

Use the universal power key marked [Y to x] or [Y^x].

This key allows you to calculate powers with arbitrary exponents.

To obtain the roots to any degree you make use of the fact that n-th root of a number X is equivalent to the number X raised to the power 1/n

10th root of X = X raised to the power 1/10

10 th root of 2345 = (2345)^ (0.1)

For this case

2345^(0.1)=2.172772644

The conversion formula is

# dB =10*log(Pout/Pin) for say an amplifier.

For your case

Pout/Pin= 10^4 then #dB =10*log(10^4)=10*4=40 dB

Let us take a less obscure exemple

# dB= 57.39, what is the power ratio?

10*log(Pout/Pin)= 57.39

log(Pout/Pin)=57.39/10=5.739

Pout/Pin=Ratio =10^(5.739)= 548276.9649, not a number you would hear or see quoted, but a correct value.

To calculate the power ratio

- Convert the decibels in Bels (divide by 10)
- While the number just calculated is still in Answer memory (ANS), press [SHIFT] [LOG] to access the the 10^x function
- Press [SHIFT][(-)] to enter (ANS)
- Close the parenthesis [)]
- Press [ENTER]

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....

Use following sequence following exactly your problem

2.998

5.874

)

2nd, 10 to power x

X

8

10 to power x

=

When evaluating a "10 to the power x" expression, you first enter the exponent number, then press the "2nd, 10 to the power" key. Same as getting the value of "sin 60", first enter 60, then the "SIN" key.

The (18/5.874) sequence in the middle has to be in (.....) is because you first have to get the value of that expression (however complicated it is) before you tell the calculator you want to raise 10 to the power of the resultant number.
