A: When you multiply two numbers, their exponents add.
So,
![64^{\frac{1}{2}} * 64^{\frac{1}{2}} = 64^{\frac{1}{2} + \frac{1}{2}} = 64^{1} = 64](https://tex.z-dn.net/?f=64%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%2A%2064%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%2064%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%2064%5E%7B1%7D%20%3D%2064)
Since 64^1/2 multiplied by itself is 64, then it is the square root of 64.
B: The area is irrational. 7 * √7 is irrational.
