Evaluate the left hand side to find the value of aa in the equation in simplest form. 6

Solution

Given the expression below

$\frac{x^{\frac{5}{3}}}{x}=x^a$

To find the value of a, we apply the exponent rule, which is

$\frac{x^m}{x^n}=x^{m-n}$

Applyin it to the expression gives

$\begin{gathered} \frac{x^{\frac{5}{3}}}{x}=x^a \\ x^{\frac{5}{3}-1}=x^a \\ x^{\frac{5-3}{3}}=x^a \\ x^{\frac{2}{3}}=x^a \end{gathered}$

Simplifying to find a

$\begin{gathered} x^{\frac{2}{3}}=x^a \\ \frac{2}{3}=a \\ a=\frac{2}{3} \end{gathered}$

Hence, the value of a is 2/3

40 PTS ! The length of the rectangle is 2 ft more than its width. The area of the rectangle is 80 square feet. Find the width of

TiliK225 [7]

Answer:

The length of a rectangle is 2 feet more than it's width. How do you find the dimensions of the rectangle if its area is 63 square feet?

Step-by-step explanation:

x(x+2) = 63

x^2 + 2x = 63

x^2 + 2x - 63 = 0

Quadratic formula with numbers plugged in: (-2 +or- sqrt(4 - 4* 1 * -63))/2 becomes

-2 +or- sqrt(256)/2 so (-2 +or- 16)/2 therefore -18/2 or 14/2. Discard negative result.

x = 7. 63/7=9. Sides are 7ft and 9ft.

The missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4 and the missing expression should be for Step 6 is 56 - 4.1

<h3>Part A: Explain what the missing expression should be for Step 3</h3>

To do this, we make use of the expression in step 2

The expression in step 2 is

[(5^2 + 3)/0.5] - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 5^2

So, we have:

[(25 + 3)/0.5] - 16.4 ÷ 4

Hence, the missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4

<h3>Part B: Explain what the missing expression should be for Step 6.</h3>

To do this, we make use of the expression in step 5

The expression in step 5 is

56 - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 16.4 ÷ 4

So, we have:

56 - 4.1

Hence, the missing expression should be for Step 6 is 56 - 4.1
