The numerical value is -9

Step-by-step explanation

Given:


\log \frac{b^3c^3}{\sqrt[]{a^3}}

This can be re-written as;


\log \frac{b^3c^3}{a^{(3)/(2)}}

Applying the laws of logarithm


\log b^3+\log c^3-\log a^{(3)/(2)}


3\log b+3\log c-(3)/(2)\log a

From the values given;

loga =10 logb=11 logc=-9

Substitute


3(11)+3(-9)-(3)/(2)(10)
=33-27-15
=-9
