plug this in. I'm going to use the calculator that just comes on most Windows computers at this point. Or you can pretty much any kind of scientific or really any calculator for the most part. But this is just pretty much the easiest thing. I kind of have to show you all how to do this. The first thing I'm gonna do is put down on base. So nine and then depending on how your calculators set up, you might have this like X to the Y, which is going to take whatever number you previously have and set that as the base and whatever number you type next is going to be your experiment, since our exponent is negative just to make sure it reads it correctly. And because sometimes some calculators have some weird kind of like operations for reading things. I'm going to put down parentheses. And now on this calculator, I first have to type two point 56 Then I'll make it negative and then close my parenthesis and then you can see up top here. This may be how you actually need to input it. So you may have this carrot symbol as opposed to this X the Y on your calculator. And then once you have that, you can just go ahead and hit equals. And then that should give you your answer. And I mean, this number just kind of goes on forever. Uh, so you can just pretty much around this to as many different places as you want, and then just kind of we'll leave your answer there.
