Question

If (x, 0) lies on the graph of y = log b x then x =

Answer 1

Given:-

$y=log_b(x)$

To find the value of x when the point is (x,0).

So now we substitute the point. so we get,

$0=log_b(x)$

So now we simplify using log formula and we get,

$\begin{gathered} log^{-1}(0)=x \\ 1=x \end{gathered}$

So the value of x is 1.
