When proving the properties of logarithms when exponents must be used, the property that is used in all of these is D. 
<h3>What property is used in proving the properties of logarithms?</h3>
When proving any property of logarithms that have to do with exponents, one property that should always be used is
.
Expressing y as a product of
is the most basic property of using exponents on logs because it has both product, quotient, and power rules of logarithms.

Answer:
(c) $72
Step-by-step explanation:
Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...
12 × 12 = 144
tiles will be needed to cover the area.
The cost of 144 tiles at $0.50 each is ...
(144)($0.50) = $72.00
