Answer: Yes, radicals can be rationals.
Step-by-step explanation:
Yes, a radical can be rational.
If a square root is a perfect square, you will obtain an integer, and by definition, the integer are rationals (they can be written as simple fractions).
Example:

If the radical has a root <em>n </em>and number inside of the root can be written as a power with exponent
, then you will obtain a radical.
Example:
![\sqrt[3]{64}=\sqrt[3]{4^{3}}=4=\frac{4}{1}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%3D%5Csqrt%5B3%5D%7B4%5E%7B3%7D%7D%3D4%3D%5Cfrac%7B4%7D%7B1%7D)
69.99
20% off of 14.99 is 119.992 then -50 is 69.992 but we round to nearest cent and sence 2 is less than five we round down so jt is 69.99$
Associative because Lenny is grouping things together to make adding easier
