The TI-30Xa has a "y^x" key located just above the divide key. To calculate 1.009 to the 17th power, press 1 . 0 0 9 y^x 1 7 =

One way to enter a fraction is almost exactly as you write it. For the example you gave, calculate it as ( 4 1 + 2 / 3 ) / 1 0 0 =

You don't want the square root. In this example, you want the sixth root.

Press 4 5 2nd [xth-root] 6 =

The xth-root is the shifted function of the y^x key, located just above the divide key.

It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2

or

b: ((SQRT61) / 2) - 7

For a:

Type 61 SQRT.

Subtract 7.

Equals.

Divide by 2.

Equals. (Should be 0.4051248...)

For b:

Type 61 then SQRT.

Then divide by 2.

Equals.

Then subtract 7.

Equals. (Should be -3.094875...)

Good luck.

The carrot button is just above the divide key on the column furthest to the right on the keyboard. It's written as "y^x" instead of "^"

ok what you are going to do is simple.. ALWAYS USE PARENTHASIES haha for example this problem is easily fixed by typing this: (x-1) divided by ((x^2)-3x+2) and that should get you your answer. the reason it didnt work was because you were trying to divide x-1 by x^2 then by -3x then by 2 and added all together and you will get an ugly answer, just remember parenthesis! :)

The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.

Because this calculator does not allow you to enter formulas, you have to alter the formula a bit.

Instead of entering 3.55*10^24, enter (10^24)*3.55

Note: 10^24 is 10 to the 24.

Here is the procedure:

1) find 10^24. Do this by typing 10, pressing the yx button (which is right above the divide button), and then typing 24. Press the '=' button.

2) multiple the result by 3.55. Press the '=' button.

You now have the answer.

(2x3^2) divided by (2x3^(-2))

just make sure to use double parenthesis around the negative exponent so that you get the right answer
