Question 697606
<pre>That's not supposed to be double exponents. Double 
exponents must have a right parenthesis between 
them. It should be

A=8000(1+.06/4)^(4*7) 

You problem is obviously a case of the compound
interest formula:

{{{A}}}{{{""=""}}}{{{P(1+r/n)^(n*t)}}}

{{{A}}}{{{""=""}}}{{{8000(1+.06/4)^(4*7)}}}

which is the formula for this problem:
<b>
If $8000 is invested at 6% compounded quarterly,
what will be the amount after 7 years?
</b>
Answer: $12137.78.
