Question
Write 15200000000000 in scientific notation.
Answer
$$ 15200000000000 = 1.52\cdot 10^{13} $$
Explanation
Step 1: Since 15200000000000 do not have a decimal point, we will add one at the end of the number 15200000000000.
15200000000000.
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).
1.5200000000000.
Step 3: We moved the decimal point 13 spaces to the right. Therefore, the exponent on base 10 will be positive 13.Now we know that the:
Mantissa = 1.5200000000000 (which can be written as 1.52 )
Exponent = 13
So, the solution is:
$$15200000000000 = \color{blue}{ 1.52} \cdot 10^{ \color{red}{ 13 }}$$This page was created using
