Answer:
the 2nd and 4th i think
Step-by-step explanation:
Are there any answer choices sorry for the wait as well lunch time
Divide the exponent inside the "√" by the exponent outside:
12/4=3, 16/4=4
so the answer is x³y^4
B is the answer.
Answer:
A. 
B. 
Step-by-step explanation:
Given expression:
Using properties of logarithm we can write the expression in various equivalent forms:
1) Using quotient rule ![[\log a-\log b=log \frac{a}{b}]](https://tex.z-dn.net/?f=%5B%5Clog%20a-%5Clog%20b%3Dlog%20%5Cfrac%7Ba%7D%7Bb%7D%5D)
:
⇒![log \frac{2}{8}]](https://tex.z-dn.net/?f=log%20%5Cfrac%7B2%7D%7B8%7D%5D)
Reducing 
to simple fraction by dividing numerator and denominator by their greatest common factor.
⇒![log \frac{2\div 2}{8\div 2}]](https://tex.z-dn.net/?f=log%20%5Cfrac%7B2%5Cdiv%202%7D%7B8%5Cdiv%202%7D%5D)
⇒![log \frac{1}{4}]](https://tex.z-dn.net/?f=log%20%5Cfrac%7B1%7D%7B4%7D%5D)
2) Plugging in 
in the expression as 
⇒ 
Using quotient rule again
⇒
We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon
Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price
We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price
Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825
Hope this helps :)</span>
