-1(5x+1)
-5x-1
the (-) in front is just a short way to put (-1)
Answer:
2376 square feet
Step-by-step explanation:
40 x 15 = 600
40 x 24 = 960
1/2 x (24 x 9) = 108
600 + 600 + 960 + 108 + 108 = 2376
Answer:
![Density = 1.094g/cm^3](https://tex.z-dn.net/?f=Density%20%3D%201.094g%2Fcm%5E3)
Step-by-step explanation:
Given
![Length = 17.7cm](https://tex.z-dn.net/?f=Length%20%3D%2017.7cm)
![Width = 8.3cm](https://tex.z-dn.net/?f=Width%20%3D%208.3cm)
![Height = 13.0cm](https://tex.z-dn.net/?f=Height%20%3D%2013.0cm)

Determine the density of the wood
First, we calculate the volume of the wood.
![Volume = Length * Width * Height](https://tex.z-dn.net/?f=Volume%20%3D%20Length%20%2A%20Width%20%2A%20Height)
Substitute values for Length, Width and Height
![Volume = 17.7cm * 8.3cm * 13.0cm](https://tex.z-dn.net/?f=Volume%20%3D%2017.7cm%20%2A%208.3cm%20%2A%2013.0cm)
![Volume = 1909.83cm^3](https://tex.z-dn.net/?f=Volume%20%3D%201909.83cm%5E3)
The density is:
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
![Density = \frac{2090g}{1909.83cm^3}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7B2090g%7D%7B1909.83cm%5E3%7D)

Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as ![2^{\frac{2}{5} } + 3^{\frac{1}{10} }](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B2%7D%7B5%7D%20%7D%20%2B%203%5E%7B%5Cfrac%7B1%7D%7B10%7D%20%7D)
// use the
to transform the expression
Convert
to
=
(here a = 2, n = 5, m = 2)
Then convert
to
=
(here a = 3, n = 10, m = 1)
Now we get
=
+
. This is the simplified form, which is the answer.
