Given :

$\displaystyle \sf{ log_{a}a }$

To find :

The value of the expression

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

$\displaystyle \sf{ log_{a}a }$

Step 2 of 2 :

Find the value of the expression

$\displaystyle \sf{ Let \: \: x = log_{a}a }$

$\displaystyle \sf{ \implies {a}^{x} = a }$

$\displaystyle \sf{ \implies {a}^{x} = {a}^{1} }$

$\displaystyle \sf{ \implies x = 1 }$

Thus we get

$\displaystyle \sf{ log_{a}a } = 1$
