Divide two scientific notation numbers
Test your understanding of divide scientific notation by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's divide these 2 scientific notation numbers
🎙️
Dividing the base coefficients of 4 and 5 gives us 0.8. Dividing the powers of ten gives us ten to the power of 3
🎙️
But 0.8 is not a proper coefficient for a scientific notation number, it is one place too small
🎙️
If we increase 0.8 to 8 and decrease our power of ten by one, we have 8 times ten to the power of 2.
