Question
Write 24400 in scientific notation.
Answer
$$ 24400 = 2.44\cdot 10^{4} $$
Explanation
Step 1: Since 24400 do not have a decimal point, we will add one at the end of the number 24400.
24400.
Step 2: 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).
2.4400.
Step 3: We moved the decimal point 4 spaces to the right. Therefore, the exponent on base 10 will be positive 4.Now we know that the:
Mantissa = 2.4400 (which can be written as 2.44 )
Exponent = 4
So, the solution is:
$$24400 = \color{blue}{ 2.44} \cdot 10^{ \color{red}{ 4 }}$$This page was created using
