Scientific notation is where people make ginormous numbers to a number inbeween ten and one. Very small numbers to, here are some examples.
6,000= 6 x 10^3
.0006= 6 x 10^-4. Hope this helped!
The first one is 1,600
the second one is 321,489
The answer is 96 + 8a I guess
The correct answer is D because you cannot have a fraction as the base of a log
hope this helps :)
