Question

cum se calculeaza lg√×+lg×=6

Answer 1

   
[tex]\texttt{lg = logaritm in baza 10} \\ \texttt{Folosim formula: } lg\,a + lg\,b \ lg(a\cdot b) \\ Rezolvare: \\ lg \sqrt{x} + lg \,x = 6 \\ lg\,x \sqrt{x} =6 \\ x \sqrt{x} = 10^6 \\ x \sqrt{x} = 1000000 \\ x \sqrt{x} = 10000 \cdot 100 \\ x \sqrt{x} = 10000 \cdot \sqrt{10000} \\ x = \boxed{10000} [/tex]
