Answer the question for the function f(x) = log10 x
Find the ratio of a to b when f(a) = 5 + f(b).
Ответ(ы) на вопрос:
[latex]f(a)=lg(a) \\ f(b)=lg(b)\\lg(a)=5+lg(b) \\ lg(a)-lg(b)=5 \\ lg \frac{a}{b} =5 \\ \frac{a}{b} =10^5[/latex]
[latex]f(x)=lgx\\ lga=5+lgb\\ lg(\frac{a}{b})=5\\ \frac{a}{b}=10^5[/latex]
