Answer:
Explanation:
The expression that you want to simplify is:
This is the simplification step-by-step:
1. Mulitply the expressions on the numerator among them and the expressions on the denominator among them:
![5x\times \frac{1}{x^{-7}}\times x^{-2}=\frac{5x\cdot x^{-2}}{x^{-7}}](https://tex.z-dn.net/?f=5x%5Ctimes%20%5Cfrac%7B1%7D%7Bx%5E%7B-7%7D%7D%5Ctimes%20x%5E%7B-2%7D%3D%5Cfrac%7B5x%5Ccdot%20x%5E%7B-2%7D%7D%7Bx%5E%7B-7%7D%7D)
2. For equal bases that are multiplying, add the exponents:
![\frac{5x\cdot x^{-2}}{x^{-7}}=\frac{5x^{1-2}}{x^{-7}}=\frac{5x^{-1}}{x^{-7}}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%5Ccdot%20x%5E%7B-2%7D%7D%7Bx%5E%7B-7%7D%7D%3D%5Cfrac%7B5x%5E%7B1-2%7D%7D%7Bx%5E%7B-7%7D%7D%3D%5Cfrac%7B5x%5E%7B-1%7D%7D%7Bx%5E%7B-7%7D%7D)
3. Pass the power on the denominator to the numerator by changing its sign (negative exponents become positive when inverted)
![\frac{5x^{-1}}{x^{-7}}=5x^{-1}x^{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%5E%7B-1%7D%7D%7Bx%5E%7B-7%7D%7D%3D5x%5E%7B-1%7Dx%5E%7B7%7D)
4. Simplify adding the exponents with the same base:
![5x^{-1}x^{7}=5x^{-1+7}=5x^6](https://tex.z-dn.net/?f=5x%5E%7B-1%7Dx%5E%7B7%7D%3D5x%5E%7B-1%2B7%7D%3D5x%5E6)
And that is the final expression in its most simple form.
Sorry I don’t kno ……………..
Answer:
D. Point D
Step-by-step explanation:
4.82 is close to 5 so D is right A and B are not even close. C is a little to close to 4.5 to be 4.82. But D looks like it could be 4.82 to though so D is right.
The volume would be 5.5 cubic units.
First, we need to find the volume of one cube. It would be LWH.
0.5 x 0.5 x 0.5 = 0.125
Now, just multiply that volume by 44.
0.125 x 44 = 5.5
