Negative one to the 4th, and then take the cube root of that. Well, negative one to the 4th is just one, and then one to the 1 3rd power, well, that's just going to be equal to one. So what we have here in blue, that's just equal to one. So we have nine times 16 minus nine times one. Well, that's just going to be nine times 15. We have 16 nines, and then we're gonna take away a nine. So that's gonna be nine times 15.
