Happy to help! We converted 0.000064 to 64 / 1,000,000 because in this situation, a fraction is easier to work with than a decimal. Once Mike had 64 / 1,000,000, he was able to simplify things by taking the cubed root of both the top and the bottom of the fraction.
If you're having a hard to time visualizing this conversion, let's say we have 0.6. We can also write this as 6/10. Similarly, if we have 0.64, we can write that as 64/100. And 0.064 would be 64/1000. So if we have 0.000064, we can write that as 64 / 1,000,000. The result of the division would be 0.000064
converting the decimals to fractions was essential. Also, for numbers with just one and zero, I didn't not know you could simply divide the number of zeros by the exponent. Very helpful.
