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:

Answer:
B
Step-by-step explanation:
The condo costs $163,000, earns $2,986 per month, spends no more than 25% of her income, then if she pays $33,000 for the down payment, the remaining amount would be $130,000. Since 20% of the initial cost is only $32,600, she can adjust her down payment to 20.25% of the initial cost so that the annual payments would be less.
