Answer:

$\displaystyle n^3-\frac{1}{n^{2}}$

Step-by-step explanation:

Exponents Properties

We need to recall the following properties of exponents:

$(a^x)^y=(a^y)^x=a^{xy}$

$\displaystyle a^{-x}=\frac{1}{a^x}$

We are given the expression:

$2^m=n$

We need to express the following expression in terms of n.

$8^m-4^{-m}$

It's necessary to modify the expression to use the given equivalence.

Recall $8=2^3 \text{ and }4 = 2^2$ . Thus:

$(2^3)^m-(2^2)^{-m}$

Applying the property:

$(2^m)^3-(2^m)^{-2}$

Substituting the given expression:

$n^3-n^{-2}$

Or, equivalently:

$\mathbf{\displaystyle 8^m-4^{-m}= n^3-\frac{1}{n^{2}}}$

Solve for x. 5x - 1 = 26 A) x= 27/5 B) 0x=5 C) x= -5

Ber [7]

5x-1= 26

5x-1+1= 26+1

5x= 27

Divide by 5 for 5x and 27

5x/5= 27/5

x= 27/5

Answer is x= 27/5 - A)

Use the formula R = 6e12.77x, where x is the blood alcohol concentration and R, as a percent, is the risk of having a car accide

kenny6666 [7]

Well, It depends. It is either the mathematical term for 100% - 50%, or 6e*Ehq8deh. So, It is either 1389D9238 or c793-sk2. So try plotting the database point. Hope this helps :)
