Question
Write 201500000 in scientific notation.
Answer
$$ 201500000 = 2.015\cdot 10^{8} $$
Explanation
Step 1: Since 201500000 do not have a decimal point, we will add one at the end of the number 201500000.
201500000.
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).
2.01500000.
Step 3: We moved the decimal point 8 spaces to the right. Therefore, the exponent on base 10 will be positive 8.Now we know that the:
Mantissa = 2.01500000 (which can be written as 2.015 )
Exponent = 8
So, the solution is:
$$201500000 = \color{blue}{ 2.015} \cdot 10^{ \color{red}{ 8 }}$$This page was created using
