Write 19500 in scientific notation.
Answer
$$ 19500 = 1.95\cdot 10^{4} $$
Explanation
Step 1: Since 19500 do not have a decimal point, we will add one at the end of the number 19500.
19500.
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).
1.9500.
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 = 1.9500 (which can be written as 1.95 )
Exponent = 4
So, the solution is:
$$19500 = \color{blue}{ 1.95} \cdot 10^{ \color{red}{ 4 }}$$This page was created using
