Answer:
32
Step-by-step explanation:
The formula needed to solve this question by hand is:
![x^{\frac{m}{n}} =\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D)
256^(5/8) = 8th root of 256^5
256^(5/8) = 8th root of 1280
<u>256^(5/8) = 32</u>
Step-by-step explanation:
Let Andrew wage be = X
Cammi earns $20 more than Andrew So Cammi earns = 20 + X
Brenda earns $30 less than twice Andrew's wage
So she earns = 2X - 30
Their total combanied wage is $400
So Andrew + Cammi + Brenda = $400
X + 20+X + 2X-30 =400
4X - 10 =400
4X=400+10
4X=410
X= $102.5
So Andrew earns $102.5
Cammi earns $122.5
Brenda earns $175
Answer:
n = 4
Step-by-step explanation:
Use the explicit formula of a arthmetic sequence: an = a1 + d(n - 1)
a1 = -70
d = -10
an = -100
Do all of the steps and plug all the numbers with the formula.
So -100 = -70 - 10(n - 1)
-100 = -70 - 10n + 10
-100 = -60 - 10n
-100 + 60 = -40
-40 = -10n
-40/-10n = -10n/10
n = 4
So the final answer is n = 4. Just follow all of the steps and you will understand how I got my answer. Hope it helped!
