Answer:
1.6* 10^5
Step-by-step explanation:
1. Move the decimal place to the left to make a number from 1 to 10.
2. Find the exponent, that is the number of times you moved the decimal.
3.Then put the number in scientific notation.
First, we'll solve A.
2 x2 = 4
3 x2 = 9
3x2=6, not 9.
So it is not A.
5 x2 = 10
7 x2 = 11
7x2=14, not 11.
So B. is out too.
It isn't D. because 12/9 is improper and 3/4 isn't.
So C. is left.
4 x2 = 8
6 x2 = 12
hope it helps!
