Write 152000 in scientific notation.
Answer
$$ 152000 = 1.52\cdot 10^{5} $$
Explanation
Step 1: Since 152000 do not have a decimal point, we will add one at the end of the number 152000.
152000.
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).
1.52000.
Step 3: We moved the decimal point 5 spaces to the right. Therefore, the exponent on base 10 will be positive 5.Now we know that the:
Mantissa = 1.52000 (which can be written as 1.52 )
Exponent = 5
So, the solution is:
$$152000 = \color{blue}{ 1.52} \cdot 10^{ \color{red}{ 5 }}$$This page was created using
