Given,
⇒log(10÷103)⇒log(10103)⇒log(101013)⇒log(10)1−13⇒log(10)23⇒23log 10⇒23.\Rightarrow \text{log}(10 ÷ \sqrt[3]{10}) \\[1em] \Rightarrow \text{log}\Big(\dfrac{10}{\sqrt[3]{10}}\Big) \\[1em] \Rightarrow \text{log}\Big(\dfrac{10}{10^{\dfrac{1}{3}}}\Big) \\[1em] \Rightarrow \text{log}(10)^{1 - \dfrac{1}{3}} \\[1em] \Rightarrow \text{log}(10)^{\dfrac{2}{3}} \\[1em] \Rightarrow \dfrac{2}{3}\text{log 10} \\[1em] \Rightarrow \dfrac{2}{3}.⇒log(10÷310)⇒log(31010)⇒log(103110)⇒log(10)1−31⇒log(10)32⇒32log 10⇒32.
Hence, log(10÷103)=23\text{log}(10 ÷ \sqrt[3]{10}) = \dfrac{2}{3}log(10÷310)=32.

Simplify the following :
log 27log 3\dfrac{\text{log 27}}{\text{log } \sqrt{3}}log 3log 27
log 9 - log 3 log 27\dfrac{\text{log 9 - log 3}}{\text{ log 27}} log 27log 9 - log 3
2 + 12\dfrac{1}{2}21log (10)-3
2log 5 + log 8 - 12\dfrac{1}{2}21log 4
