Question
Write 1500 in scientific notation.
Answer
$$ 1500 = 1.5\cdot 10^{3} $$
Explanation
Step 1: Since 1500 do not have a decimal point, we will add one at the end of the number 1500.
1500.
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).
1.500.
Step 3: We moved the decimal point 3 spaces to the right. Therefore, the exponent on base 10 will be positive 3.Now we know that the:
Mantissa = 1.500 (which can be written as 1.5 )
Exponent = 3
So, the solution is:
$$1500 = \color{blue}{ 1.5} \cdot 10^{ \color{red}{ 3 }}$$This page was created using
