Question

If log10 y = 2. what does y equal?

Answer 1

Answer:

$log_{10} (100) = 2$

Step-by-step explanation:

Here, the given expression is:

$log_{10} (y) = 2$

Now, by logarithm rules, we know

if  $log_{b}(x) = z$

, then x =$b^{z}$

Comparing here, b = 10  and  z = 2

⇒ y  =   $10^{2} = 100$

or, $log_{10} (100) = 2$
