Alright, so if we wanted to take, for example, cell phone owners per 100 people and compare Germany to the USA, we can start by making up a number for Germany - 80 - and a number for the USA - 70. Next, the ratio of people using cell phones is 80/70=8/7 with the numerator being the people from Germany and the denominator being the number from the USA.

Answer:

(2x^3)^3=8\cdot x^{9}

Step-by-step explanation:

<u>Properties of Exponents</u>

The property called Power to a Power shows us how to simplify expressions of the type:

(x^n)^m=x^{n*m}

Similarily the property called Power of a product simplifies expressions like:

(x.y)^n=x^n.y^n

The company mentioned in the question uses the expression

(2x^3)^3

millimeters per second to calculate the maximum capacity of a photocell with an area of x^3 square millimeters.

First, use the power of a product property:

(2x^3)^3=2^3\cdot (x^3)^3

Now use the power to a power property:

(2x^3)^3=2^3\cdot x^{3*3}

Operate:

\mathbf{(2x^3)^3=8\cdot x^{9}}

Rachel spends 1/4 of her money
astra-53 [7]

Step-by-step explanation:

Let's start by defining our term:

How much she had at the beginning = B

Now let's edit that value like the problem says

B - B/4 - B/8 = 40

Let's multiply everything by 8 to get rid of any denominators

8B - 2B - B = 320

5B = 320

B = 64

Answer:

Rachel had $64 at the beginning.
