Question
Write 0.018 in scientific notation.
Answer
$$ 0.018 = 1.8\cdot 10^{-2} $$
Explanation
Step 1: Move the decimal point from its current position (the black dot) to a position immediately to the right of the first nonzero digit (the red dot).
0.01.8
Step 2: We moved the decimal point 2 spaces to the left. Therefore, the exponent on base 10 will be negative 2.Now we know that the:
Mantissa = 1.8
Exponent = -2
So, the solution is:
$$0.018 = \color{blue}{ 1.8} \cdot 10^{ \color{red}{ -2 }}$$This page was created using
