For this case we have that by power properties it is fulfilled:

(a ^ n) ^ m = a ^ {n * m}

Now, we can rewrite the expression as:

\frac {64g ^ 9 * h ^ 6 * k ^ {12}} {8g ^ 3 * h ^ 2} -h ^ {25} k ^ {15} =

We also have by definition of properties of powers that:

\frac {a ^ m} {a ^ n} = a ^ {m-n}

So:

8g ^ {9-3} * h ^ {6-2} * k ^ {12} -h ^ {25} k ^ {15} =\n8g ^ 6 * h ^ 4 * k^(12) -h^(25) * k^(15)

One wall on Zoe's bedroom is 5 feet wide and 8 feet tall.Zoe puts up a poster of her favorite athlete.the poster is 2 feet wide and 3 feet tall.How much of the wall is not covered by the poster

Answers

To find area you multiply legnth times width so 5x8=40 sq ft
Then 2x3=6 sq ft which is the area of the poster. Then 40 - 6 = 34sq ft.
Your answer is 34 sq ft

Mario ordered a pizza for dinner when it arrived, mario quickly ate 1/8 of the pizza.while mario went to go get napkins, his pet poodle ate 1/3 of the pizza.a.about what percent of the pizza is left

Answers

Answer:  54.16% of pizza is left.

Step-by-step explanation:

Since we have given that

Part of pizza ate by Mario = (1)/(8)

Part of pizza ate by his pet = (1)/(3)

So, total part ate by them is given by

(1)/(8)+(1)/(3)\n\n=(8+3)/(24)\n\n=(11)/(24)

Part of pizza left is given by

1-(11)/(24)\n\n=(24-11)/(24)\n\n=(13)/(24)

Percentage of pizza left is given by

(13)/(24)* 100\n\n=(1300)/(24)\n\n=54.16\%

Hence, 54.16% of pizza is left.

1/8 of the pizza is about 12% and 1/3 is about 33%.  So if 45% of the pizza was eaten by Mario and his dog, there is about 55% left.

(If 1/4 means 25% then 1/8 is half of that 12.5% exactly but I used 12% since we are estimating)

What is (3k+2)(k-3)?

Answers

I think that you have to foil that.

Therefore:

3k(k-3) 2(k-3)
3k^2-9k+2k-6
3k^2-7k-6 (Combine like terms and that is your final answer)

(3-7n^2+3n^3)-(6n^3-1-5n^2). Simplify.

Answers

Simplify

3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)

Simplify brackets

3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Collect like terms

(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)

Simplify

4 - 2n^2 - 3n^3

Answer:

-3n^3 - 2n^2 + 4.

Step-by-step explanation:

(3-7n^2+3n^3)-(6n^3-1-5n^2)

First distribute the negative over the second parentheses:

= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Now simplify like terms:

= -3n^3 - 2n^2 + 4 (answer).

Answer:

w = 21

x = 13

y = -11

z = -16

Step-by-step explanation:

Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...

Thus, w = 17 - (-4) = 17 + 4 = 21

x = 12 - (-1) = 12 + 1 = 13

y = -3 -8 = -11

z = -2 -14 = -16

These are the values of w, x, y and z , respectively.
