Answer:
![\Huge \boxed{-15y-9}](https://tex.z-dn.net/?f=%5CHuge%20%5Cboxed%7B-15y-9%7D)
Step-by-step explanation:
To solve this problem, first you have to use the distributive property of
.
First, expand.
![\displaystyle -2(5y+6)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-2%285y%2B6%29)
![-2*5=-10](https://tex.z-dn.net/?f=-2%2A5%3D-10)
![\displaystyle -2*6=-12](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-2%2A6%3D-12)
![\displaystyle -10y-12](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-10y-12)
![\displaystyle -10y-12+3-5y](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-10y-12%2B3-5y)
Next, solve.
![\displaystyle -10-12+3-5=\boxed{-15y-9}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20-10-12%2B3-5%3D%5Cboxed%7B-15y-9%7D)
In conclusion, the correct answer is -15y-9.
Answer:
We conclude that:
![\sqrt[5]{8^3}=8^{\frac{3}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B8%5E3%7D%3D8%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D)
Step-by-step explanation:
Given
We are given the expression
![\sqrt[5]{8^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B8%5E3%7D)
To determine
Solve using fractional law exponent rule
Given the expression
![\sqrt[5]{8^3}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B8%5E3%7D)
Apply radical rule: ![\sqrt[n]{a}=a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
![\sqrt[5]{8^3}=\left(8^3\right)^{\frac{1}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B8%5E3%7D%3D%5Cleft%288%5E3%5Cright%29%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D)
Apply exponent rule: ![\left(a^b\right)^c=a^{bc}](https://tex.z-dn.net/?f=%5Cleft%28a%5Eb%5Cright%29%5Ec%3Da%5E%7Bbc%7D)
![=8^{3\cdot \frac{1}{5}}](https://tex.z-dn.net/?f=%3D8%5E%7B3%5Ccdot%20%5Cfrac%7B1%7D%7B5%7D%7D)
Multiply the exponent: 3 × 1/5 = 3/5
![=8^{\frac{3}{5}}](https://tex.z-dn.net/?f=%3D8%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D)
Therefore, we conclude that:
![\sqrt[5]{8^3}=8^{\frac{3}{5}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B8%5E3%7D%3D8%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D)
