Answer:
a factor of 2 is shown, but 4 was factored out
Step-by-step explanation:
The difference of squares is factored as ...
a² -b² = (a +b)(a -b)
Then the given difference of squares factors as ...
144x² -100 = (12x)² -10² = (12x +10)(12x -10)
Each of these factors has a factor of 2 that can be factored out:
= (2(6x +5))(2(6x -5))
= (2·2)(6x +5)(6x -5)
= 4(6x +5)(6x -5)
The first factor should be 4, not 2.

Answer:10000
Step-by-step explanation:
Remember that log x and 10^x are inverse functions.
If you have log x = 4 and want the value of x, write this out:
log x 4
10 = 10
This simplifies to:
x = 10^4, and so the fourth answer choice is the correct one.
