So this four times four is the same thing as four squared. And so you're going to be left with five minus three, or negative three plus five fours. And so, three of these in the denominator are going to cancel out with three of these in the numerator. And so notice, when you multiply this out, you're going to have fiveįours in the numerator and three fours in the denominator. So it's times four times four times four times four times four. And then four to the fifth, that's five fours being Four to the negative 3 power, that is one over four to the third power, or you could view that as one over four times four times four. And that's just a straightįorward exponent property, but you can also think about why does that actually make sense. Four to the negative three plus five power which is equal to four See look, I'm multiplying two things that have the same base, so this is going to be that base, four. Well there's a couple of ways to do this. And I encourage you to pause the video and think about it on your own.
So, let's think about whatįour to the negative three times four to the fifth power is going to be equal to.
Let's get some practice with our exponent properties, especially when we have integer exponents.
