Answer:

It would cost $1.37 less per copy if you buy the set.

Step-by-step explanation:

In order to find the price for the set of 6 books we will set up an equation to do so.

$6b=41.25$

Next we can solve for b

$b=\frac{41.25}{6} \\\\b=6.875\\b=6.88$

As we are using money, we must round b up in order to retain the needed 2 decimal places.

Now we can find the difference from the price of a single book compared to the price of the set

$8.25-6.88=1.37$

Answer:

So, the step1 is correct.

Step-by-step explanation:

The expression is

$(6 x^3 + 8 x^2 - 7 x)-(2x^2 + 3)(x- 8)\\\\(6 x^3 + 8 x^2 - 7 x) - (2x^3 - 16 x^2 + 3 x - 24)\\\\6 x^3 + 8 x^2 - 7 x - 2 x^3 - 16 x^2 + 3 x - 24\\\\4 x^3 - 8 x^2 - 4 x - 24$

So, the step 1 is correct.

What to the tenth power can get you 300

OLEGan [10]

Answer:

1.7689 (rounded to 4 decimal places)

Step-by-step explanation:

Let the number we are seeking be "x", thus we can write the equation as:

$x^{10}=300$

Since we have raised "x" to the "10th power", to get "x" back again, we need to take 10th root. Same goes for right side, we take 10th root of 300. We will get our answer. The process shown below:

$x^{10}=300\\\sqrt[10]{x^{10}} =\sqrt[10]{300} \\x=\sqrt[10]{300} \\x=1.7689$

hence, 1.7689 raised to 10th power will give us 300
