Answer:
2 120 500 9. so 2,629 would be the answer
Property of addition I think
Answer:
Step-by-step explanation:
To find the value of x, isolate it on one side of the equation.
<h3>5>x/5</h3>
<u>First, you have to switch sides.</u>
→ x/5<5
<u>Then, you multiply by 5 from both sides.</u>
→ 5x/5<5*5
<u>Solve.</u>
<u>Multiply the numbers from left to right.</u>
→ 5*5=25
<u>→ x<25</u>
- <u>Therefore, the solution is x<25, which is our answer.</u>
I hope this helps you! Let me know if my answer is wrong or not.

b=9
Rationalizing the denominator of ![\frac{\sqrt[3]{2z} }{\sqrt[3]{z^2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B2z%7D%20%7D%7B%5Csqrt%5B3%5D%7Bz%5E2%7D%20%7D)
we get
.
Option D is correct.
Step-by-step explanation:
We need to rationalize the denominator: ![\frac{\sqrt[3]{2z} }{\sqrt[3]{z^2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B2z%7D%20%7D%7B%5Csqrt%5B3%5D%7Bz%5E2%7D%20%7D)
Solving:
![\frac{\sqrt[3]{2z} }{\sqrt[3]{z^2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B2z%7D%20%7D%7B%5Csqrt%5B3%5D%7Bz%5E2%7D%20%7D)
using Radical rule: ![\frac{\sqrt[n]{x}}{\sqrt[n]{y}}=\sqrt[n]{\frac{x}{y} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5Bn%5D%7Bx%7D%7D%7B%5Csqrt%5Bn%5D%7By%7D%7D%3D%5Csqrt%5Bn%5D%7B%5Cfrac%7Bx%7D%7By%7D%20%7D)
![=\sqrt[3]{\frac{2z}{z^2}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B2z%7D%7Bz%5E2%7D%7D)
![=\sqrt[3]{\frac{2}{z^{2-1}}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B2%7D%7Bz%5E%7B2-1%7D%7D%7D)
![=\sqrt[3]{\frac{2}{z^{1}}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B2%7D%7Bz%5E%7B1%7D%7D%7D)
![=\sqrt[3]{\frac{2}{z}}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B2%7D%7Bz%7D%7D)
We can write it as:
![\frac{\sqrt[3]{2} }{\sqrt[3]{z} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B2%7D%20%7D%7B%5Csqrt%5B3%5D%7Bz%7D%20%7D)
So, rationalizing the denominator of ![\frac{\sqrt[3]{2z} }{\sqrt[3]{z^2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B2z%7D%20%7D%7B%5Csqrt%5B3%5D%7Bz%5E2%7D%20%7D)
we get
.
Option D is correct.
