Hey there and welcome to HP Calcs. I’m

Rick and today we’re gonna have a look at how to do exponents on the Texas

Instruments TI-30X IIS calculator. To do this we’ll be using the following keys:

the x squared key located here, the up arrow key or the caret key located here,

and the negative key located here in case we want to do a negative exponent.

All right we’ll start off with the basics, if you want a square number, let’s

say 5 squared we would enter the number and then the x squared key you see five

squared on the top line there and then hit the enter equals sign and we get 25

which we know is the correct answer. If we want to cube a number we need to use

the up arrow or carrot key. If you want five cubed we would enter 5, up arrow,

3 equals 125 which is the correct answer so we can use this key the up arrow or

carrot key anytime we have an exponent that isn’t 2. If we want to do a negative

exponent, let’s say 5 to the power of negative 2, we would enter the 5 the up

arrow or carrot the negative and the 2 and then press equals and we get 0.04

which is correct. If we wanted to do an exponent that is a fraction we can also

do this by entering say if we wanted 4 to the power of 1/2 start with 4, up

arrow, bracket, 1, /, 2, bracket there’s our half, equals

which gives us 2 which is correct because we know that an exponent of 0.5

is the same thing as a square root. All right I hope this was helpful and good

luck on those tests!

Rick, I love my TI-30XIIS very much.

But did you know that my same-year Sharp EL-506W is the identical shirtpocket-size as the TI-30XIIS, —but the Sharp has a Solver, and many more scientific features that the identical-sized TI does not. For now, the EL-506W is my always-carry scientific, (until I find the all-around perfect scientific calc)… /Regards

Thank you!!

Totally helpful! Thanks

THANKS A LOT! GReAT VIDEO FAST and EASY EXPLANATION! YEA, IM YELLING! IM EXITED! I JSUT GTO THIS CALCULATOR! LOL

Thank youuuu

Is there any way to get the answer with exponent ?

Thank you! Thank you! Thank you!

Great video 😀

You're the best! You got straight to the point.

like it cause it gets to the point and doesn't have a bunch of useless-talk.

Thanks!!!!
