Question 766502
{{{(1/4 )log (2, 16) + (1/2) log (2, 49) = log (2, x)}}}

{{{log (2, 16^(1/4 ))+  log (2, 49^(1/2)) = log (2, x)}}}

{{{log (2,root(4,16))+  log(2,sqrt(49)) = log (2, x)}}}

{{{log (2, root(4,2^4))+  log (2, 7) = log (2, x)}}}

{{{log (2, 2)+  log (2, 7) = log (2, x)}}}

{{{log (2, 2*7) = log (2, x)}}}

{{{log (2, 14) = log (2, x)}}} => {{{x=14}}}
