Answer:
![3\sqrt[4]{5}](https://tex.z-dn.net/?f=3%5Csqrt%5B4%5D%7B5%7D)
Step-by-step explanation:
Given: ![\frac{\sqrt[4]{810} }{\sqrt[4]{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B4%5D%7B810%7D%20%7D%7B%5Csqrt%5B4%5D%7B2%7D%20%7D)
Top and bottom has fourth root. so we take fourth root in common
![\sqrt[4]{\frac{810}{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cfrac%7B810%7D%7B2%7D%20%7D)
When we divide 810 by 2. we will get 405
![\sqrt[4]{405}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B405%7D)
Now we simplify the fourth root
405 can be written as 3*3*3*3*5
![\sqrt[4]{3*3*3*3*5}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B3%2A3%2A3%2A3%2A5%7D)
![3\sqrt[4]{5}](https://tex.z-dn.net/?f=3%5Csqrt%5B4%5D%7B5%7D)
Answer:
km
Step-by-step explanation:
We are given;
- The are of a rectangle as 7/10 km²
- Width of the rectangle is 1/3 km
We are required to find the length of the rectangle;
We need to know how to find the area of a rectangle first;
Area of rectangle = Length × Width
Rearranging the formula;
Length = Area of rectangle ÷ Width
= 7/10 km² ÷ 1/3 km
We get;


(improper fraction)
Thus, the length of the rectangular park is
km

Answer:
0.625lb bag of bird seeds
Step-by-step explanation:
She starts with a 3.5 lb bag,
Then she uses 3/4 of the bag, so find the remaining amount in the bag, which would be 1/4 of the original weight;
1/4 * 3.5
= 1/4 * 7/2
= 7/8
Then she removes 0.25 lbs of weight, hence take away 0.25 (the amount removed) from 7/8 (the current weight of the bag).
7/8 - 0.25
= 7/8 - 1/4
= 7/8 - 2/8
= 5/8
So she has a 5/8lb bag of bird seeds or a 0.625lb bag.
