Answer:
The amount the $20.000 will be worth in 17 years at compound interest is $65068.443
Step-by-step explanation:
Here we have the Principal, P = $20,000.00
The annual interest rate, r = 7% = 0.07
Time , t = 17 years
Number of compounding period per year, m = quarterly = 4
The compound interest can be found from the following formula;

Therefore, by plugging the values of the equation parameters, we have;

Therefore, the amount the $20.000 will be worth in 17 years at compound interest = $65068.443.
The equivalent expression is 
<h3>How to determine the equivalent expression?</h3>
The expression is given as:
rootindex 5 startroot 1,215 endroot superscript x
Rewrite properly as:
![\sqrt[5]{1215^x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B1215%5Ex%7D)
Apply the law of indices

Hence, the equivalent expression is

The number of the zeroes of the function will be 3. Then the zeroes of the functions are -2, 1, and 2.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
f(x) = x³ - x² - 4x + 4
Then the factor of the equation will be
f(x) = x²(x - 1) - 4(x - 1)
f(x) = (x² - 4)(x - 1)
f(x) = (x² - 2²)(x - 1)
f(x) = (x + 2)(x - 2)(x - 1)
Then the solution to the equation will be
(x + 2)(x - 2)(x - 1) = 0
x = -2, 1, 2
The number of the zeroes of the function will be 3. Then the zeroes of the functions are -2, 1, and 2.
