For this case we must simplify the following expression:

$(6x) ^ 2$

By definition of power properties we have to:

$(ab) ^ n = a ^ n * b ^ n$

So, according to the mentioned property we have to:

$(6x) ^ 2 = 6 ^ 2 * x ^ 2 = 36x ^ 2$

So, the initial expression can be simplified as:

$36x ^ 2 = (36x) * x$

Answer:

$36x ^ 2 = (36x) * x$

Answer:

5 pounds

Step-by-step explanation:

Given that:

Amount of gift card = $80

Cost of coffee per pound = $8.24

Amount left in the card = $38.80

To find:

Number of pounds of coffee bought = ?

Solution:

Let the number of pounds of the coffee bought = $x$ pounds

Cost of 1 pound = $8.24

Cost of $x$ pounds = $8.24 $\times x$

Writing the equation as per question statement:

$80 - 8.24x = 38.80\\\Rightarrow 80 - 38.80 = 8.24x\\\Rightarrow 8.24x = 41.2\\\Rightarrow x = \dfrac{41.2}{8.24}\\\Rightarrow \bold{x = 5\ pounds}$

Therefore, 5 pounds of coffee was bought.
