Question

If log10 y = 2. what does y equal?

Answer 1

`log_(10)  (100) = 2`

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`
