Answer:
All real numbers greater than -3
Step-by-step explanation:
The domain of a log is the baseline is greater than 0.
Set x + 3 greater than zero and solve
x + 3 > 0
x > -3
The root

can be converted into the power

. Therefore we can rewrite the problem as

and then follow the exponent rules about a power to a power, multiplying 1/2 and 3/4 together.
Thus the problem becomes

, which then can be turned into
![\sqrt[8]{10} ^{3x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B10%7D%20%5E%7B3x%7D)
, making the last option our answer.
The answer is .....................1600......
Answer:
25.48 days
Step-by-step explanation:
For a radioactive substance, the Amount of the substance remaining A(t) is modeled by the equation

where

In the given problem:
Half Life of the Radioactive Isotope = 8
Initial Amount,
=100%=1
A(t)=11% =0.11
Therefore substituting in the model above:

The farmer need to wait for 25.48 days
