Answer: B: (y + z = 6) × -5
Step-by-step explanation:
if you multiply 'y' by -5 it turns into -5y. Therefore when you add -5y and 5y together, you get 0y which is what you want when eliminating the y-term.
Answer:
2
Step-by-step explanation:
We have to get the value of the expression of - ∛(- 8).
Now, we can write the expression as
- ∛(- 8)
=![-\sqrt[3]{-8}](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7B-8%7D)
= 
{Converting into exponent form}
= ![-[(-2)^{3} ]^{\frac{1 }{3} }](https://tex.z-dn.net/?f=-%5B%28-2%29%5E%7B3%7D%20%5D%5E%7B%5Cfrac%7B1%20%7D%7B3%7D%20%7D)
{Since (- 2) × (- 2) × (- 2) = - 8}
= ![- [(-2)^{3\times \frac{1}{3} } ]](https://tex.z-dn.net/?f=-%20%5B%28-2%29%5E%7B3%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%5D)
{Since we know that ![[x^{a}] ^{b} = x^{ab}](https://tex.z-dn.net/?f=%5Bx%5E%7Ba%7D%5D%20%5E%7Bb%7D%20%3D%20x%5E%7Bab%7D)
}
= - [- 2]
