Question about Texas Instruments TI-30 XIIS Calculator

Ad

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.

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

Quick-Start Guide
When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator.
Variables
Any lowercase letter may be used as a variable.
Exponents
Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses.
Parentheses and Brackets
Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression.
Multiplication, Addition, and Subtraction
For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ).
Order of Operations
The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error.
Division, Square Root, Radi cals, Fractions
Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

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)

1/a^n=a^(-n) and 1/a^(-n)=a^n

Example: a^(-3)=1/(a^3)

1/(a^(-4))=a^(-(-4))=a^4

I have this problem. The whole menu disappears. It seems to drop out of its own accord.

Three things that help 1. Enabling Launch Manager in Services 2. Search for Launch Manager > open > select and add apps using the ADD button (you can set it to Launch Manager so you always open the little console) 3. Put a shortcut to Launch Manager on Desktop and keep an eye on it.

Use the (-) key for negative numbers (not just exponents) instead of the - key. The - is to subtract one value from another, (-) is to input a negative value.

Hello,

The calculator applies the rules during the internal calculations. But all it shows you is the (final) result. It does not keep track of what exponents you used to get to the result. It is not capable of doing symbolic manipulations.

Hope you are not too disappointed.

For 5 to the 6th power, type

5 ^ 6 =

You should get 15625

5 ^ 6 =

You should get 15625

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
