I can identify and use inverses to solve equations with one variable

Answer:
[tex] \boxed{ y = 10000}[/tex]
Step-by-step explanation:
[tex] \boxed{question \: 1.} \\ log(y) + 100 = 104 \\ log(y) = 104 - 100 \\ log(y) = 4 \\ but \: log(x) = log_{10}(x) \to \\ log_{10}(y) = 4 \\ y = 10 {}^{4} \\ \boxed{ y = 10000}[/tex]
