To solve the problem we must know the basic exponential properties.
<h3>What are the basic exponent properties?</h3>
![\sqrt[m]{a^n} = a^{\frac{n}{m}}](https://tex.z-dn.net/?f=%5Csqrt%5Bm%5D%7Ba%5En%7D%20%3D%20a%5E%7B%5Cfrac%7Bn%7D%7Bm%7D%7D)
The expression can be written as ![x^9\sqrt[3]{y}](https://tex.z-dn.net/?f=x%5E9%5Csqrt%5B3%5D%7By%7D)
.
Given to us
Using the exponential property,
Using the exponential property ,
![=x^9\times y^\frac{1}{3}\\\\=x^9\times \sqrt[3]{y}\\\\=x^9 \sqrt[3]{y}](https://tex.z-dn.net/?f=%3Dx%5E9%5Ctimes%20y%5E%5Cfrac%7B1%7D%7B3%7D%5C%5C%5C%5C%3Dx%5E9%5Ctimes%20%5Csqrt%5B3%5D%7By%7D%5C%5C%5C%5C%3Dx%5E9%20%5Csqrt%5B3%5D%7By%7D)
Hence, the expression can be written as .

Answer:
Step-by-step explanation:
2/3x(-4)=20
2/3x*4=20
8/3x=20
8/3x/8/3= 20/8/3
0.83 but 3 is repeting
Answer:
3+4 = 5+2
Step-by-step explanation:
They equal each other when they are added up.
Profit = 8%
If the briefcase was marked down 20% from 1500 you multiply 1500 x .2 = 300 in order to calculate the discount.
Calculate the discounted price:
1500 - 300 = 1200
Calculate 10% discount of 1200:
1200 x .1 = 120
Calculate the sales price:
1200 - 120 = 1080
The last step is to calculate the profit/loss is the cost is 1000.
The briefcase sold for 1080 and the company paid 1000 for it, so there was a profit of 80.
The percentage is calculate by dividing 80/1000 = 8% profit
4:85 is the answer because if u subtract 1 hour and 30 minutes
