### My problem involves converting in chemistry and im just trying to figure out how to do a problem 0.58 x 6.022 x 10 raised to the 23/ 1. I know how to calculate the problem just cant read the answer a more...

Press the keys:
. 5 8 * 1 2 . 0 1 x^-1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER
and you should get 2.9E22. Do you get something different?

* is the multiply key on the right, between divide and subtract.

x^-1 is on the left, below MATH.

EE is the 2ND function of the , key, just above the 7.

Another way to calculate this is:
. 5 8 / 1 2 . 0 1 * 6 . 0 2 2 2ND [EE] 2 3 ENTER

This should give you the same result.

### I ask my TI-83 Plus to calculate (-64)^(3/2) The TI-83 Plus says the answer is -512i, but I think the answer should be 512i. Is the calculator wrong or am I?

You're both right, in a way. (-64)^3 is -262144. The square root of that is +/- 512i. Take your choice as to the sign.

For what it's worth, the TI-84, TI-86, TI-89, and the HP 50g all go with the negative value.
