Which expression is equivalent to a^m divide a^n?(20points)

Citrus2011 [14]

<h3><u>Answer</u> :</h3>

$\bigstar\:\boxed{\bf{\dfrac{a^m}{a^n}=a^{m-n}}}$

<h3><u>Learn More</u> :</h3>

$\dag\sf\:\:a^m\times a^n=a^{m+n}$

$\dag\sf\:\:\dfrac{a^m}{a^n}=a^{m-n}=\dfrac{1}{a^{n-m}}$

$\dag\sf\:\:a^{-m}=\dfrac{1}{a^m}$

$\dag\sf\:\:(a^{m})^n=a^{mn}$

$\dag\sf\:\:a^1=a$

$\dag\sf\:\:a^0=1$

$\dag\sf\:\:\sqrt[n]{a^m}=a^{\frac{m}{n}}$

How can you inscribe a regular polygon in a circle?

dalvyx [7]

Answer:

For a shape to be inscribed means that it's area is smaller than that of the other shape. Essentially, it's one shape inside another.

View my crudely drawn example for visualization. There, the square-ish shape is inscribed in the circle.

(You can basically inscribe any shape within another.)

sergey [27]

Answer:

The total cost is $345

Step-by-step explanation:

Zoe purchased a barbecue grill originally priced at $600

Discount % = 50%

So, cost after discount = $600-50\%(600)$

Cost after discount =300

Sales tax in Fairfax is 15%

So, cost including tax = 300+0.15(300)

Cost including tax = 345

Hence The total cost is $345

2. Let f(x) = 2x² + 2. Find each of the following:<br> a. f(-3)<br> b. f(6)<br> c. f(-1)<br> d. f(4)

r-ruslan [8.4K]

Answer: The answers are in the steps please look carefully.

Step-by-step explanation:

To solve for each value input the value into the function and solve to find f(x)

A. f(-3) = 2(-3)^2 + 2

f(-3) = 2(9) + 2

f(-3) = 18 + 2

f(-3) = 20

B. f(6) = 2(6)^2 + 2

f(6) = 2(36) + 2

f(6) = 72+ 2

f(6) = 74

C. f(-1) = 2(-1)^2 + 2

f(-1) = 2(1) + 2

f(-1)= 2 + 2

f(-1) = 4

D. f(4) = 2(4)^2 + 2

f(4) = 2(16) + 2

f(4) = 32 + 2

f(4) = 34
