Question
Write 109.00000026 in scientific notation.
Answer
$$ 109.00000026 = 1.0900000026\cdot 10^{2} $$
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).
1.09.00000026
Step 2: We moved the decimal point 2 spaces to the right. Therefore, the exponent on base 10 will be positive 2.Now we know that the:
Mantissa = 1.0900000026
Exponent = 2
So, the solution is:
$$109.00000026 = \color{blue}{ 1.0900000026} \cdot 10^{ \color{red}{ 2 }}$$This page was created using
