Answer:
r2 means r x r
Step-by-step explanation:
2 is an exponent, meaning that the number (what r is) will multiply twice, meaning r x r.
For example, if r was 4, then you would multiply 4 x 4, which is 16 and not 4 x 2, which is 8.
Many make this mistake, which can cause big trouble. As you saw in the example above, products are not the same.
Hope this helps! :)
