Answer:
what are the equations
Step-by-step explanation:
you didnt show the equations
To convert our number to scientific notation, we are going to move the decimal point to the right until we have only one non-zero digit to the left of the decimal point, and then, we are going to multiply that number by a negative power of 10 equal to the number of times we moved the decimal point to the right:
<span>
Our number is 0.000000016, so we need to move the decimal point 8 times to the right to have </span>only one non-zero digit to the left of the decimal point (1.6). Since we moved the decimal point eight times to the right, we are going to multiply 1.6 by y a negative power of 10 equal to the number of times we moved the decimal point to the right i.e.
![10^{-8}](https://tex.z-dn.net/?f=10%5E%7B-8%7D)
.
So 0.000000016 expressed in scientific notation is 1.6x
![10^-8](https://tex.z-dn.net/?f=10%5E-8)
, or in calculator notation 1.6E-8
We can conclude that the correct answers are <span>
1.6E-8 and </span><span>
1.6 × 10-8</span>
