7-24.

Solve each of the following equations.

$15(x−2)^{3.7}=50$
Step 1(a):
$(x-2)^{3.7}=\frac{50}{15}$
Step 2(a):
$x-2=\left(\frac{50}{15}\right)^{1/3.7}$

$3\log_4(x-2)=6$
Step 1(b):
$\log_4(x-2)=2$
Step 2(b):
$4^2=x-2$

$\log_3(x)-\log_3(x-2)=2$
Step 1(c):
$\log_3\left(\frac{x}{x-2}\right)=2$
Step 2(c):
$3^2=\frac{x}{x-2}$
