Question

If formula"> P = x, $log_{2}$ Q = y, and $log_{2}$ R = z, write in term of x, y, z.
$log_{2} \frac{P^{2} Q}{R^{3} }$

Answer 1

Answer:

The answer is 2x + y - 3z

Step-by-step explanation:

∵ $log_{2}P=x$

∵ $log_{2}Q=y$

∵ $log_{2}R=z$

∵ $log_{2}\frac{P^{2}Q}{R^{3}} =$

  $log_{2}P^{2}+log_{2}Q-log_{2}R^{3} =$

  $2log_{2}P+log_{2}Q-3log_{2}R$

∴ 2x + y - 3z
