Simplify completely. Leave your answer in exponential form:
stich3 [128]

Answer:

{2}^{3}  \times  {4}^{3}  \times 9

Step-by-step explanation:

Using the division rule when dealing with exponents

\frac{b {}^{h} }{b {}^{j} }  = b {}^{h - j}

meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.

so using that we are going to do 2, 4 and 9

\frac{2 {}^{8} }{ {2}^{5} }  =  {2}^{8 - 5 = 3 \:  \:  \:  \:  \: 2 {}^{3} }

\frac{ {4}^{4} }{ {4}^{1} }  =  {4}^{4 - 1}  \:  \:  \:  {4}^{3}

\frac{9 {}^{9} }{ {9}^{8} }  =  {9}^{9 - 8}  = 9 {}^{1}

Combine all the terms and we get

{2}^{3} \times 4 {}^{3}  \times  {9}

The monthly salary of mr nadir is $6723.50 and his monthly expenditure is $3854.75. how much does he save in one year.
levacccp [35]

The one year savings of Mr. Nadir is $. 34, 425

Given:

Mr. Nadir Monthly salary = $6723.50

His monthly Expenditure = $3854.75

Now we have to find the savings amount of each month.

For that, first we have to calculate the remaining amount he has after spending the expenditure.

To calculate the remaining amount we have to subtract the expenditure from the total amount that's is his salary.

So,

Remaining amount = Salary - Expenditure

Remaining amount = 6723.50 - 3854.75

=> 2868.75

So, for one year he must save the amount

=> 2868.75 x 12 = 34425

What is the rate of change?<br> X<br> у<br> 0<br> 4<br> 1.<br> 4.<br> 2.<br> 4.
satela [25.4K]
<h2>Answer:</h2>

The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values  

The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.

<h2>Step-by-step explanation:</h2>

I know <u>it`s not the answer</u> but I hope it helps a little Δ    Δ
