0.00023

Move the decimal point to the right, so it stops between 2 and 3, and the power of 10 becomes negative.

= 2.3 * 10⁻⁴

Option b.

I hope this helps.

Scientific notation is a method to write numbers with many digits in a more summarized way.
A number written in scientific notation follows the following pattern:
m x 10 ^ e
The number e is the order of magnitude, the number m must be greater than or equal to 1 and less than 10.
The following numbers are written in scientific notation:
a. 0.15 x 104
b. 7.06 x 10-8
The following numbers are NOT written in scientific notation:
c. 3.3 x 10 ^ 012
Because they do not follow the pattern mentioned.
