SOURCE: How do you perform calculations with large

Hello,

You do them the same way as you would for any exponent, except that you calculator has a limited capacity. If results exceeds 10^100 calculator gives an overflow error.

In case you are interested, the result is 6.75821x10^(176). That is clearly more than you calculator can handle. And don't go calculating n! for n larger or equal to 70.

Hope it helps.

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.

The key you are looking for looks like y raised to the exponent x. It is below the "hyp" key. To determine an exponent, enter you base, hit the y to the x key and enter the exponent.

For example, 3 to the power of 4, enter 3, hit the y to the x key, and enter 4 and hit the = key.

Good luck.

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

To enter this equation on a TI89Titanium is rather trivial: You use the keyboard and the [ALPHA] key to enter the variable (or unknown) n.

The question I am asking you is this: "What do you intend to do with the equation once it is entered?"

As you can see on the screen capture I am enclosing, if you just want to enter it and if n does contain a value already, all the calculator will do is to echo the command without modification. Obviously this is not what you want.

The screen capture shows you two other commands you can use solve( and expand (.

That should answer your question concerning how to enter the equation (look at the command line) and maybe help you decide what you want to do with the equation once it is entered.

2n = 1st even integer

2n + 2 = 2nd even integer

Product = 2n(2n + 2) = 4n^2 + 4n = 4(n^2 + n)

1520 = 4(n^2 + n)

1520/4 = 4(n^2 + n)/4

380 = n^2 + n

0 = n^2 + n - 380

0 = (n + 20)(n - 19)

n = -20, +19

Answer can not be negative so n = +19

2n = 2(19) = 38

2n + 2 = 2(19) + 2 = 40

ANSWER: the integers are 38 and 40

2n + 2 = 2nd even integer

Product = 2n(2n + 2) = 4n^2 + 4n = 4(n^2 + n)

1520 = 4(n^2 + n)

1520/4 = 4(n^2 + n)/4

380 = n^2 + n

0 = n^2 + n - 380

0 = (n + 20)(n - 19)

n = -20, +19

Answer can not be negative so n = +19

2n = 2(19) = 38

2n + 2 = 2(19) + 2 = 40

ANSWER: the integers are 38 and 40

Hello,

You do them the same way as you would for any exponent, except that you calculator has a limited capacity. If results exceeds 10^100 calculator gives an overflow error.

In case you are interested, the result is 6.75821x10^(176). That is clearly more than you calculator can handle. And don't go calculating n! for n larger or equal to 70.

Hope it helps.

Uh yes it will allow you to enter a negative exponent.... press the numbers you want then hit EXP button, then hit the +/- button and then the exponent. 60 % of the time, it works...... everytime.

As there can realistically be only 2 firing orders for a 4 cylinder engine then it will be one of these two.
1-2-4-3
1-3-4-2
I am 95% sure that on your Ford it will be 1-2-4-3. So give that a try and if it is incorrect then you know it it 1-3-4-2.

The 12 v conversion is the way to go. 6 v is a pain. It's getting harder and harder to get parts, and running off of battery power leaves a lot to be desired, especially if you've ever had to haul a dead battery back to the barn. I had a Farmall model "B", 1947, 6 volts. 12 volts was like a whole different tractor. Just my humble opinion!
