Answer:

1. 2^9 = 512

2. 2^3 = 8

3. 7^3 = 343

4. 6^3 = 216

5. 3^6 = 729

Step-by-step explanation:

To start we have to express the number as a multiplication of prime numbers, from there we can take the expression as a power

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512

2^9 = 512

2 x 2 x 2 = 8

2^3 = 8

7 x 7 x 7 = 343

7^3 = 343

6 x 6 x 6 = 216

6^3 = 216

3 x 3 x 3 x 3 x 3 x 3 = 729

3^6 = 729

Solve for k. k/2 +1/2=3

ikadub [295]

Answer:

$k = 5$

Step-by-step explanation:

Solve for $k$ :

$\frac{k}{2} + \frac{1}{2} = 3$

-Multiply both sides of the equation by the denominator $2$ :

$2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2$

$k + 1 = 6$

-Subtract both sides by $1$ :

$k + 1 - 1 = 6 - 1$

$k = 5$

So, the value of $k$ is $5$ .

A clear box has the shape of a rectangular prism and is filled with sand. Find the volume if the box

Strike441 [17]

Answer:

24 m³

Step-by-step explanation:

Since you didn't state the dimensions of the rectangular prism, and you didn't add a picture to show it's dimensions, then permit me to assume dimensions for the question

Assuming it's breadth is 2 m.

Assuming it's length is 4 m.

Assuming it's height is 3 m

Then the volume of a rectangular prism is given as l * b * h. Which means we multiply all the sides by one another. From my assumption of values, we have that 2 * 3 * 4, and this gives us 24 m³

24 m

Now what you'd do is substitute your values for my assumed values.. Cheers
