Answer:
480 is the answer
Step-by-step explanation:
Answer:
- 15, - 16
Step-by-step explanation:
-15 + (-16) = - 15 - 16 = - 31
-3 + 3n = -6 - 6n. Expand the brackets
3n + 6n = -6 + 3. Collect like terms
9n = -3
n = -3/9 = -1/3
For this case we have:
By properties of the radicals 
So:
.
Now, for power properties we have:

Thus, 
So:
in its radical form
Answer:
in its simplest form.
