Write 7000 in scientific notation.
Answer
$$ 7000 = 7\cdot 10^{3} $$
Explanation
Step 1: Since 7000 do not have a decimal point, we will add one at the end of the number 7000.
7000.
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).
7.000.
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 = 7.000 (which can be written as 7 )
Exponent = 3
So, the solution is:
$$7000 = \color{blue}{ 7 } \cdot 10^{ \color{red}{ 3 }}$$This page was created using
