Which of the following expressions is correctly written in scientific notation?
sashaice [31]

Answer:

The Answer is A. 1.4 x 10^5

Step-by-step explanation:

Numbers in Scientific notation have the first number between 1 and 9 and then the decimal, followed by the rest of the numbers. Find the power of 10 by moving the decimal one place a time from right to left until the decimal is between the last number and the next to last.

B. is wrong because the number is .32 x 10^3 instead of 3.2 x 10^2

C. is wrong because it is 2 to the 10th power (2^10) instead of a power of 10

D is wrong because the number is 11.2 x 10^1 instead of 1.12 x 10^2

Hope this helps!! Have an Awesome Day!! :-)
