Question
Write 224 in scientific notation.
Answer
$$ 224 = 2.24\cdot 10^{2} $$
Explanation
Step 1: Since 224 do not have a decimal point, we will add one at the end of the number 224.
224.
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).
2.24.
Step 3: 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 = 2.24
Exponent = 2
So, the solution is:
$$224 = \color{blue}{ 2.24} \cdot 10^{ \color{red}{ 2 }}$$This page was created using
