Question 1062570
{{{ log( 4,9 ) = y }}}
{{{ log( 3,4 ) = x }}}
------------------
Writing the inverse:
(1) {{{ 4^y = 9 }}}
(2) {{{ 3^x = 4 }}}
-----------------
By substitution:
{{{ ( 3^x )^y = 9 }}}
{{{ 3^(x*y) = 9 }}}
{{{ x*y = 2 }}}
------------------
Maybe there is a way to prove the answer.
I don't know what that is.
