Question 959642
{{{ log( 81, 3 ) }}}
This is asking:
" What is the exponent that I raise the base {{{ 81 }}} to
that will give me the answer {{{ 3 }}}
I can restate this as:
{{{ 81^x = 3 }}}, where
{{{ x = log( 81,3 ) }}}
----------------------
{{{ x = 1/4 }}} because
{{{ root( 4, 81 ) = 3 }}}
Raise both sides to the 4th power
{{{ ( root( 4,81 ) )^4 = 3^4 }}}
{{{ 81 = 81 }}}
Hope this helps
A good thing to remember is:
"Logs are exponents"
