Question

Write 0.00000000018 in a scientific notation

Answer 1

Answer:

$1.8*10^{-10}$

Step-by-step explanation:

To find the number in scientific notation you want to find how many times you have to move the decimal to get the decimal to be right after the first non-zero number. If you move to the left the exponent is positive and if you move it to the right the exponent is negative. The answer would be $1.8*10^{-10}$.
