<h2>Rules of Exponents</h2>

There are many rules that apply to operations involving exponents. In this question, we'll need the following:

<h3>The division rule</h3>
  • ⇒ \dfrac{a^n}{a^m}=a^{n-m}

<h2>Solving the Question</h2>

We're given:

z^{21}\div z^7=z^k (solve for k.)

⇒ Rewrite as a fraction:

\dfrac{z^{21}}{z^7}=z^k

⇒ Use the division rule:

z^{21-7}=z^k\\z^{14}=z^k\\14=k

Therefore, the value of <em>k</em> is 14.

<h2>Answer</h2>

<em>k</em> = 14

The function V(t)= 1,000(1.06)^2t models the value of an investment after t years.
RideAnS [48]

Answer:

It's 1,000

Step-by-step explanation:

exponential form is f(x)= a × b^2

(a=initial amount)

(b=growth rate)

you would replace a for 1000 and b for .06 (+1)

v(t)=1000(1.06)^2t

therefore the initial amount is 1000

if this didnt help sorry lol
