Write 0.615 in scientific notation.
Answer
$$ 0.615 = 6.15\cdot 10^{-1} $$
Explanation
Step 1: 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).
0.6.15
Step 2: We moved the decimal point 1 spaces to the left. Therefore, the exponent on base 10 will be negative 1.Now we know that the:
Mantissa = 6.15
Exponent = -1
So, the solution is:
$$0.615 = \color{blue}{ 6.15} \cdot 10^{ \color{red}{ -1 }}$$This page was created using
