So to find the value of v to the nearest 10, we need to use a calculator.
00:06
And on your calculator, you'll have a button that says sign on it, and written above that button, it'll say sign to the negative one power.
00:19
So whatever button you use to get to the words that are written on your calculator instead of the button.
00:24
On mine, up in the top left -hand corner, i have to hit the second button.
00:30
So when you hit second, and then you hit the sign button, what should appear on your calculator is this.
00:39
And then you have to type this decimal in there.
00:42
So inverse sign is what that's called, .5127.
00:48
And then you just press the equals button.
00:52
So let me do that on my calculator, .5127.
00:58
And it tells me an answer of 30 .8438433...
