Question
Write 24.4 in scientific notation.
Answer
$$ 24.4 = 2.44\cdot 10^{1} $$
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).
2.4.4
Step 2: We moved the decimal point 1 spaces to the right. Therefore, the exponent on base 10 will be positive 1.Now we know that the:
Mantissa = 2.44
Exponent = 1
So, the solution is:
$$24.4 = \color{blue}{ 2.44} \cdot 10^{ \color{red}{ 1 }}$$This page was created using
