Answer:
y = ( [tex]\frac{10}{x}[/tex] )³
Step-by-step explanation:
log(y) + 3log(x) = 3
log(y) + log(x³) = 3
log(x³y) = 3
[tex]log_{10}[/tex] (y) + 3[tex]log_{10}[/tex] (x) = 3
[tex]log_{10}[/tex] (y) + [tex]log_{10}[/tex] (x³) = 3
[tex]log_{10}[/tex] (x³y) = 3 ⇔ 10³ = x³y ⇔ y = ( [tex]\frac{10}{x}[/tex] )³
