Question
Write 80100000 in scientific notation.
Answer
$$ 80100000 = 8.01\cdot 10^{7} $$
Explanation
Step 1: Since 80100000 do not have a decimal point, we will add one at the end of the number 80100000.
80100000.
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).
8.0100000.
Step 3: We moved the decimal point 7 spaces to the right. Therefore, the exponent on base 10 will be positive 7.Now we know that the:
Mantissa = 8.0100000 (which can be written as 8.01 )
Exponent = 7
So, the solution is:
$$80100000 = \color{blue}{ 8.01} \cdot 10^{ \color{red}{ 7 }}$$This page was created using
