2log b 10−log b 2
Solution
The expression you provided is "2log b 10−log b 2". To simplify this, we can use the properties of logarithms. Here are the steps:
-
Apply the power rule of logarithms, which states that log_b(a^n) = n * log_b(a), to the first term:
2log_b(10) becomes log_b(10^2) = log_b(100).
-
So the expression becomes log_b(100) - log_b(2).
-
Next, apply the quotient rule of logarithms, which states that log_b(a) - log_b(c) = log_b(a/c):
log_b(100) - log_b(2) becomes log_b(100/2) = log_b(50).
So, "2log b 10−log b 2" simplifies to "log_b(50)".
