Assuming x is really x^3;
∛729 = 9
The differences of cube rule states: x³-y³= (x-y)(x²+xy+y²)
(x)³-(9)³=(x-9)(x²+9x+9²)
=(x-9)(x²+9x+81)
Hope I helped :)
Here's the "compound amount" formula:
A = P (1 + r/[n]) ^ (nt).
Mama52's comment, above, would be true EXCEPT that the base should be (1 + 0.038/2), which produces a different result:
Thus, the compound amount, with principal $4000, at 3.8%, compounded 2x per year, for 7 years, is
A = $4000 ( 1 + 0.038/2) ^ (7*2), or $5205.93 (answer)
