The band needs $800 for new uniforms and of that, they only raised $512.
Set up a proportion
and plug everything you know in.
= 
Solve for x by cross multiplying and dividing.

51200 ÷ 800 = 64
x = 64
The school band has raised 64% of their goal already.
Answer:

Step-by-step explanation:
The expression to simplify in this problem is
![7\sqrt[4]{80pq^2r^8}](https://tex.z-dn.net/?f=7%5Csqrt%5B4%5D%7B80pq%5E2r%5E8%7D)
Which can be rewritten as

Or also as

Now we can apply the following rule for the calculation of the power of a power:

So we get:

Which can therefore be rewritten as

And so, we get

which can be finally rewritten as
