if log10 y = 2. what does y equal?

Answer:
[tex]log_{10} (100) = 2[/tex]
Step-by-step explanation:
Here, the given expression is:
[tex]log_{10} (y) = 2[/tex]
Now, by logarithm rules, we know
if [tex]log_{b}(x) = z[/tex]
, then x =[tex]b^{z}[/tex]
Comparing here, b = 10 and z = 2
⇒ y = [tex]10^{2} = 100[/tex]
or, [tex]log_{10} (100) = 2[/tex]
