so to plug this in, I'm just going to use the calculator that comes on most Windows computers at this point, Um, or you just use pretty much any kind of scientific calculator if you want. And the steps that I do on here should pretty much follow the same. So first thing we're gonna do is put down our base, which is going to be seven. Then we'll come over here and hit this X to the Y. And if you're a regular, doesn't have this. It may have, like this carrot simple that you see in the top corner. Um, then notice how we have a negative to the power. So what I'm going to do just to kind of be safe, that it actually registers it because, you know, sometimes it gets a little weird is I'm going to put parentheses down, Um, so we may not need to pump the princesses, but I would say it's better safe than sorry. Uh, we're first going to plug in our number, and then I'm going to turn it negative. And I'm going to close my princes and up top here. You can see, um, how it is formatted and this may be how you also plug it into whatever calculate you have. And then we're just gonna hit, equals, and then this is going to give us our answer. And I mean, it kind of goes on forever. I'm pretty sure, but this is just where the calculus kind of ends off. So then just kind of rounded to how many other decimal places you want and then just kind of call it a day there.
