 OK, so this is a problem we just made up. It's solved for t, right? So yeah, let's do it together, right? So to solve for t, that means that everything except for t has to be on one side of the equation, of course, OK? So we can do it stepwise, or we can just isolate t altogether. So let's do it both ways, OK? So what was the first step, did we say? Divide both sides by 206, yeah. So when we do that, what happens to this side over here? It's not t3, it's called t cubed, right? So t cubed equals 12.7 times 10 to the 14, 6.7 times 10. OK, so how do I get rid of a cube? Oh, it's going to be, so here we'll take the cube root of that, right, and also take the cube root of that. So when we do that, the cube root is the inverse of q. So that's going to give us t over here. And over here, it's going to do just what it says, right? 6.1, 7 times 10 to the 12 cube root. OK, so how do I do this on my calculator? That's the real question, right? So in order to do this on your calculator, you want to think about it a little different, OK? Cube root is actually to the 1 third, yeah. So what you'll do is take this and raise it all to the 1 third. And so I have that number in my calculator. You just do the little carrot sign. And then I put parentheses around 1 divided by 3. And I get this number. So this number here has three sig figs. This one has three sig figs. So our answer is going to have three sig figs. So 1.10 has hit a wrong button or something like that. But it makes sense, right? Yeah. It makes sense, OK, cool. So I guess in your, well, I hate to give it away, you know, but I'm sure you realize what to do in that problem. Oh, yeah, I know. I just, I must have put it wrong. OK, sure. Any other questions on this one?
