another way himself times himself.. A few of my exponent friends did a lot more [Number 7 in class with other students]
- 00:41
than I did my homie 3, the exponent, cubed whatever number was hanging out with him.
- 00:46
In other words their number became itself times itself times itself. 2 cubed [Number 8 trapped inside a cube]
- 00:52
could become 8. 3 cubed could become 27.. and so on. We were in charge of creating
