CPM Homework Help : PC Problem 5-54

Solve each of the following equations.

$\log_{5}\left(25\right) + 4 \log_{2}\left(x\right) = \log_{3}\left(81\right)$
Step 1(a):
$\log_{5}5^{2} + 4\log_{2}x = \log_{3}3^{4}$

$200\left(x-3\right)^{4.2}=5000$
Hint (b):
1. Divide both sides by $200$ first.
2. Raise both sides of the equation to the $\frac{1}{4.2}$ power.
