CPM Homework Help : A2C Problem 13-136

Step 1 (a):

Subtract 1 from both sides.

$\small x^{-\frac{4}{3}}=16$

Step 2 (a):

$\text{Raise both sides to the} -\frac{3}{4}\text{ power.}$

Step 3 (a):

$\text{Now raise }\frac{1}{8}\text{ to the }-\frac{1}{3}\text{ power.}$

Answer (a):

Step 1 (b):

Simplify the second log.

log(A) − log(100)

Step 2 (b):

Remember that 100 is 10 to the 2nd power.
