Answer

$log_{2}$ (60/15) = 2

Work Step by Step

1. The law needed for this problem is $log_{a}$($\frac{A}{B}$) = $log_{a}$(A) - $log_{a}$(B). 2. Convert the equation to $log_{2}$ (60/15). 3. Solve the Function $log_{2}$ (4) , which gives you 2. 4. Or you can convert to exponents, if that is better. 5.$ 2^{x}$ = $\frac{60}{15}$ or $ 2^{x}$ = 4 6. Solving for X gives you 2.
