It is quadratic equation.
First we have find delta given by formula: delta=
where our
a=16
b=-24
c=7
so, delta=
Because delta is positive, there is real results.
Now we can use next formula x=
, to find roots (results, 2 results because its quadratic equation and delta is greater than 0)
x1=
x2=

Answer:
The correct answer is option D:
Step-by-step explanation:
Given:
log(y)= 3.994
Solution:
A logarithm base b of a positive number x satisfies the following definition:
For
Also if no base b is indicated, the base of the logarithm is assumed to be 10 .
Thus, in log(y)= 3.994 base b is not indicated. so its base is assumed to be 10
now
Then
