For this case we have the following expression:
By definition of properties of powers and roots we have to:
![a ^ {\frac {m} {n}} = \sqrt [n] {a ^ m}](https://tex.z-dn.net/?f=a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D%20%3D%20%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D)
Then, we can rewrite the expression as:
![\sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
Answer:
![4 ^ {\frac {3} {8}} = \sqrt [8] {4 ^ 3}](https://tex.z-dn.net/?f=4%20%5E%20%7B%5Cfrac%20%7B3%7D%20%7B8%7D%7D%20%3D%20%5Csqrt%20%5B8%5D%20%7B4%20%5E%203%7D)
Answer:
no, janet could not have won 10 games because 3x is not equal to 24
Step-by-step explanation:
if janet won twice as many as nadia that means nadia times 2
so it would be 20 to add both nadia and janet it would be over 24 therefore the answer is d
hope this helps

Answer:
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
Step-by-step explanation:
On the first situation there was a decrease of 25% from the previous value, this mean that the present value is 100 - 25 = 75 % from what it was before. In order to calculate the previous value we can apply a rule of three as follows:
x -> 100%
75,000 -> 75%
x*75 = 75,000*100
x*75 = 7,500,000
x = 7,500,000/75 = 100,000
On the second situation there was an absolute increase of 78 - 65 = 13, this value represents the rate we want to know. In order to find the rate we can apply a rule of three as follows:
65 -> 100 %
13 -> x
1300 = 65*x
65*x = 1300
x = 1300/65 = 20 %
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
