And so we're looking at the integral of x to the three force power dx.
00:08
And i like the way they set it up because as long as you understand the antiderivative is what you're doing, you just add one to your exponent.
00:19
And then you multiply by the reciprocal of your new exponent.
00:25
And you'll get the correct answer.
00:27
So we're already ready to do it because we have a rational exponent.
00:30
Now, if you're bad at adding fractions, well, add.
00:35
I think one shouldn't be too bad, but if you're having issues, just get the same denominator.
00:39
Well, four force is equal to one.
00:41
So i think it's pretty clear from that that the numerator, or sorry, the exponent would be three plus four, seven.
00:48
The denominator stays the same, and then you multiply by the reciprocal of that exponent...
