Answer to Question #84146 in General Chemistry for Mikey
10^(7.82x) = 381.7(8.56+7.31)
Note: Logarithms and exponentials will feature prominently throughout the course and understanding how to solve these types of equations (and knowing how to use your calculator) is essential.
10^7.28x = 381.7(8.56+7.31)
So, at first let‘s open brackets at the right side:
10^7.28x = 6 057.579
There is a main method, when:
A^f(x) = B, and f(x) = logAB.
Let’s use it: 7.28x = log_10(6057.579) (on many calcs log10 is “lg”)
7.28x = 3.782
x = 3.782/7.28 ~ 0.5195
