Simple question about writing a log--how does the root go turn to divison?
I understand the product, quotient and power laws of logarithms. But this piece in the book has me stumped. It says how they used logarithms to rewrite calculations and make them easier to figure out. Fair enough. But I'm not sure how part of it happens! (and the book sucks at expanding/explanation!)
(31.7^5 x 0.64 / 171.8)^1/3
becomes
1/3{5log31.7 + log0.64 - log171.8}
I understand what is inside of the braces, but how can the exponent come down in front like that
I can understand {5log31.7 + log0.64 - log171.8}^1/3 but not what is stated!
