Step-by-step explanation:
Answer: 6 minutes
Step-by-step explanation: the 52 seconds rounds up to a full minute so it is 5.52 rounded up to 6 minutes
Given:
The expression is:
![\left(x^{\frac{2}{5}\right)^n](https://tex.z-dn.net/?f=%5Cleft%28x%5E%7B%5Cfrac%7B2%7D%7B5%7D%5Cright%29%5En)
To find:
The decimal value of n so that the value of the given expression is equal to x.
Solution:
We have,
![\left(x^{\frac{2}{5}\right)^n](https://tex.z-dn.net/?f=%5Cleft%28x%5E%7B%5Cfrac%7B2%7D%7B5%7D%5Cright%29%5En)
This expression is equal to x.
![\left(x^{\frac{2}{5}\right)^n=x](https://tex.z-dn.net/?f=%5Cleft%28x%5E%7B%5Cfrac%7B2%7D%7B5%7D%5Cright%29%5En%3Dx)
![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)
On comparing the exponents, we get
![\dfrac{2}{5}n=1](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7Dn%3D1)
![2n=5](https://tex.z-dn.net/?f=2n%3D5)
![n=\dfrac{5}{2}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B5%7D%7B2%7D)
![n=2.5](https://tex.z-dn.net/?f=n%3D2.5)
Therefore, the required value of n is 2.5.
Answer:
39 apples
Step-by-step explanation:
45 is 3/4 or 75% of an hour. So, multiply 52 by 75% to find the answer.
75% ÷ 100 = 0.75
52 x 0.75 = 39
