Write 320 in scientific notation.
Answer
$$ 320 = 3.2\cdot 10^{2} $$
Explanation
Step 1: Since 320 do not have a decimal point, we will add one at the end of the number 320.
320.
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).
3.20.
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 = 3.20 (which can be written as 3.2 )
Exponent = 2
So, the solution is:
$$320 = \color{blue}{ 3.2} \cdot 10^{ \color{red}{ 2 }}$$This page was created using
