Which of the following numbers are written in scientific notation ?
a) 0.641×10^3
b) 2×10^1
c) 9.999 ×10^4
d) 4.38 ×5^10

I believe B. 2x10^1 is written in scientific notation as the formula for writing numbers in scientific notation states that the actual number must be in between the range of 1-10. And thus can't be less than 1 or greater than or equal to 10, I believe.
