Question 274430
how to solve each of these questions 
a.) 2x=1/32 
Multiply both sides by (1/2)
x = (1/2)(1/32)
x = 1/64
--------------------------------
b.) 120x=25
Divide both sides by 120 to get:
x = 25/120
x = 5/24
---------------- 
c.) (4/9)^x= 81/16
Invert the left side:
(9/4)^-x = (9/4)^2
----
-x = 2
x = -2
