So what is eight to the 4 3rd power? I'll do it over here. So eight to the 4 3rds is equal to eight to the 1 3rd to the 4th power. These are just exponent properties here. Eight to the 1 3rd, the cube root of eight, or eight to the 1 3rd power, that's two, because two to the 3rd power is eight. And two to the 4th power, well, two to the 4th power is equal to 16. So eight to the 4 3rds is 16.
