You can combine all the feet together 10+5+11=26 feet

Combine all the inches together -3-4-11=-18 inches=-2 ft + 6 inches

26 ft -2ft +6 inches =24 ft +6 in=24.5 ft

You can also multiply each inch -value by 1/12

10-3/12+5-4/12+11-11/12=10+5+11 -(3+4+11)/12=26-18/12, continue

Calculators work to base '10' not base '12', so you'll have to convert. the S.I. unit of measurement is used for calculators which is metres and they are base '10'. The metre was calculated by a french bloke who got the calculation wrong, but they still use it. Feet and inches are better.

If you have the so-called **xRoot key** you procede as follows; 10[xRoot] 1.797

If you do not have an xRoot key you use the equivalence** nth root of x= x to the power of 1/n**

In the case of the 10th root you type (**1.797)^(1/10)** or **(1.797)^(0.1).** Here the **[^] caret** is the **general power key**. On some calculators it is marked as [**X^y] or [Y^x]**

If you do not have an xRoot key you use the equivalence

In the case of the 10th root you type (

11^27 = 13,109,994,191,499,930,367,061,460,371 which is 29 digits long.

You can get this result from the Windows calculator (scientific view) by entering 11 and then pressing x^y 27 = . Then use Mod 29 = to get the result, which is 8.

Unfortunately the Casio fx-991ms (as with most other calculators) doesn't have nearly enough digits to cope with this type of calculation. You therefore need to split the calculation down into more manageable chunks, as follows, which works on most calculators:

First calculate 11^3 = 1,331 and work out Mod 29, which is 1,331 - 45×29 = 26.

Then calculate 26^3 = 17,576 and work out Mod 29, which is 17,576 - 606×29 = 2.

Finally calculate 2^3 = 8. Since this is less than 29, it is also the final answer as confirmed above.

This method can be used with any power number that can be factorised into numbers that don't cause the available digits of the display to overflow. In this case 27 = 3×3×3 so each step involves cubing the previous answer.

General shortcut.

If the concentration is of the form 1* 10^ (-a) where a is an integer between 0 and 14, the pH is given by a.

c= 1.* 10^(-5), pH=5

c=1.*10^(-11(, pH=11.

For other values, ex: c=3.68 *10^(-8)

pH: 3.68 [EXP] [+/-] 8 [LOG] [+/-] Result is 7.434

Above, the [+/-] key is the change sign key, just above the [7] key.

Hello,

Your TI83 calculator is a powerful machine but it does not do symbolic algebra. Results are always displayed in decimal form

(Did you notice that i**t does not have a %key.**)

Some new (not very expensive) calculators can do that : Casio FX-300es, Casio FX-115es,Casio FX-991ms or es. These type of calculators are known as NATURAL DISPLAY, or WRITE VIEW (from Sharp).

Hope it helps.

Hello

Use the general power key labelled as [^], or [X to the y] or [Y to the x] depending on calculator.

3500000 [ / ] [(]7.5 [^] 20[)] [=] gives 1.103678993 E -11

Hope it helps.

use the "carrot" button, ^. Type in 4^.5 and you get 2. If you are going to use fractions, use the division bar and parenthesis and not the fraction key. Example 4^(1/2) = 2
