Step-by-step explanation:
6.3%
that is the correct answer
Answer:
x = 2
Step-by-step explanation:
Taking antilogs, you have ...
2³ × 8 = (4x)²
64 = 16x²
x = √(64/16) = √4
x = 2 . . . . . . . . (the negative square root is not a solution)
___
You can also work more directly with the logs, if you like.
3·ln(2) +ln(2³) = 2ln(2²x) . . . . . . . . . . . write 4 and 8 as powers of 2
3·ln(2) +3·ln(2) = 2(2·ln(2) +ln(x)) . . . . use rules of logs to move exponents
6·ln(2) = 4·ln(2) +2·ln(x) . . . . . . . . . . . . simplify
2·ln(2) = 2·ln(x) . . . . . . . . . . . subtract 4ln(2)
ln(2) = ln(x) . . . . . . . . . . . . . . divide by 2
2 = x . . . . . . . . . . . . . . . . . . . take the antilogs

Answer:
c=7
Step-by-step explanation:
How to solve your problem
8=−3+29
8=−3c+298=-3c+298=−3c+29
Solve
1
Subtract
29
292929
from both sides of the equation
8=−3+29
8=−3c+298=-3c+298=−3c+29
8−29=−3+29−29
8−29=−3c+29−298{\color{#c92786}{-29}}=-3c+29{\color{#c92786}{-29}}8−29=−3c+29−29
2
Simplify
3
Divide both sides of the equation by the same term
4
Simplify
Solution
=7
