Ronch [10]

Answer:

$\boxed{−0.074031268}$

Step-by-step explanation:

$if \: this \: is \: your \: question \to \\ \: \frac{3}{2} +log \: ( \frac{8}{10}) -log \: 30 \\ then \: to \: simplify \: we \: \to \\ \frac{3}{2} + log( \frac{ \frac{8}{10} }{30} ) = \\ \\ \frac{3}{2} + log( \frac{8}{300} ) \\ .......................................................\\ now \: lets \: solve \: for \to \: log( \frac{8}{300} ) \\ ....................................................... \\ log( \frac{8}{300} ) \to \\ −1.574031268 \\ so \\ 1.5−1.574031268\\ \boxed{ans = −0.074031268}\\$
