Perform an experiment in which you flip a switch 2,300,000 times. Write this number in scientific notation.
O A. 23 x 10-6
O B. 2.3 x 106
O C. 0.23 x 105
O D. 0.23 x 106

B. 2.3 x 10⁶

Explanation:

To calculate scientific notation for the number 2,300,000, we have to follow this notation

Step 1 :

To find a we have to write the non-zero digits placing a decimal after the first non-zero digit.

Step 2 :

Now, to find b count how many numbers of digits are there to the right of the decimal.

Hence, there are 6 digits to the right of the decimal.

Step 3 :

Since, we had found the value of a and b, we can now reconstruct the number into scientific notation.

a = 2.3

b = 6

Therefore, option b is correct.
