Answer:
1) C. 2
2) A. 2
Step-by-step explanation:
1. We need to descompose 256 into its prime factors:
We must rewrite the expression ![\sqrt[8]{256}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B256%7D)
:
![=\sqrt[8]{2^8}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B8%5D%7B2%5E8%7D)
We need to remember that:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
Then:
2. Let's descompose 16 into its prime factors:
We must rewrite the expression ![\sqrt[4]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B16%7D)
:
![=\sqrt[4]{2^4}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B4%5D%7B2%5E4%7D)
Then we get:

Step-by-step explanation:
The height of the tree was 56 inches.
We can calculate the percentage of a certain amount by :
Subtracting New - Original / New multiplied by 100
this implies it will be
75 - x / 75 × 100 = 25 %
7500 - 100 x = 1875
this implies 7500 - 1875 = 100 x
5625 = 100 x
Thus , On dividing both sides by 100 we get
56.25 = x
Now on rounding off this number we will get
56 = x
Thus the original height of the corn plant was 56 inches
