The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
Answer:
You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.
Step-by-step explanation:
You have 3 1/4 pizzas. If you get rid of 3/4 of a pizza, you will end up with 2 2/4 pizzas.
To make it easier, you can just change the values into improper fractions: 3 1/4 = 13/4
13/4 - 3/4 = 10/4
10/4 = 2 2/4 pizzas
(2 2/4 = 2 1/2)
Anyways! You now have 2 and a half pizzas. You have 3 times the amount of pizza that your friend has. In other words, your friend has 1/3 the amount of pizza that you have. You can solve for this in two ways, whichever way you solve it is up to you.
- You can solve this problem by dividing the amount of food you have by 3:
which equals 0.8333... (the 3 is repeating). But you can just keep your final answer in fraction form if you want to: ![\frac{2.5}{3} = \frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7B3%7D%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
- You can solve this problem by multiplying 1/3 to the amount of food you have:
![\frac{1}{3} * 2 \frac{2}{4}\\=\frac{10}{12}\\ =\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%2A%202%20%5Cfrac%7B2%7D%7B4%7D%5C%5C%3D%5Cfrac%7B10%7D%7B12%7D%5C%5C%20%3D%5Cfrac%7B5%7D%7B6%7D)
You have 2 and 1/2 pizzas and your friend has 5/6 of a pizza.

Answer: 48
Step-by-step explanation: To find the range of the data set shown here, remember that the range is the difference between the greatest number in the data set and the least number in the data set.
<em>Greatest number</em> → 64
<em>Least number → </em>16
Now, we need to subtract 16 from 64.
64 - 16 = 48
Therefore, the range of the data set is 48.
Answer:
x=-1
Step-by-step explanation:
8/x+2=2/x-4
8/x=2/x-6
8=2-6x
6=-6x
-1=x
