Question
Write 73100 in scientific notation.
Answer
$$ 73100 = 7.31\cdot 10^{4} $$
Explanation
Step 1: Since 73100 do not have a decimal point, we will add one at the end of the number 73100.
73100.
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).
7.3100.
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 = 7.3100 (which can be written as 7.31 )
Exponent = 4
So, the solution is:
$$73100 = \color{blue}{ 7.31} \cdot 10^{ \color{red}{ 4 }}$$This page was created using
