Answer:
8.6 x 10^(-10)
Explanation:
To write 8.6E-10 in scientific notation, you would express it as a number multiplied by a power of 10. In scientific notation, the number should be between 1 and 10 (inclusive), and the power of 10 represents the magnitude of the number.
In this case, 8.6E-10 is already in scientific notation, and it represents the number 8.6 multiplied by 10 raised to the power of -10. So, in standard scientific notation, it is written as:
8.6 x 10^(-10)
