Question

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

Answer 1

`\boxed{ y = 10000}`

Explanation:

`\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}`
