Answer:
5f - 3, I'm assuming there was a typo in the answer choices.
Step-by-step explanation:
10f - 5f + 2 - 5
5f - 3
the last step is wrong because we multiply the powers in this case we do not subtract them.
we use power subtract in division.
we use power multiplication when we raise to power and the root is power like square root of x
so
![\sqrt[3]{x} = {x}^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20%20%3D%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
in our case
this step is wrong
![2x \times \sqrt[3]{ \frac{2}{y} \times \frac{y}{y} }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7By%7D%7By%7D%20%7D%20%20)
it should be
![2 x \times \sqrt[3]{ \frac{2}{y} \times \frac{ {y}^{2} }{ {y}^{2} } }](https://tex.z-dn.net/?f=2%20x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%7By%7D%5E%7B2%7D%20%7D%7B%20%7By%7D%5E%7B2%7D%20%7D%20%7D%20)
so we get
![2x \times \sqrt[3]{2 {y}^{2} \times \frac{1}{ {y}^{3} } }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%7By%7D%5E%7B3%7D%20%7D%20%20%7D%20)
![= \frac{2x}{y} \times \sqrt[3]{2 {y}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B2x%7D%7By%7D%20%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%7D%20)

notice, the length cannot be a negative value.. so is not -17
Answer:
Second choice
and the last 2 choices
Step-by-step explanation:
32m/16m=2 and our constant is 3 not 2 so not choice A
4m^2/2m=2m so possible 6m/2m=3 so choice B
4m/2m=2 and our constant is 3 not 2 so not choice C
10m/5m=2 same reason as A and C
10m^2/5m=2m possible...15m/5m=3 so choice E
32m^2/16m=2m and 48m/16m=3 so this last choice too
Answer:
12
Step-by-step explanation: If you made x, 4 and y, 5 then all equations would make sense if you change the letters to numbers.
IF
(3*4)+(4*10)=52
and
(5*4)+10=30
then
<h2>
(8*4)-2*10=<u><em>
12</em></u></h2><h2 />
