You can put this solution on YOUR website! What is the answer for:
log10(100*10 to the -6)=
---
log10(100*10^-6)
---
log10(10^-4)
---
= -4
=====================================
log10 to the 8 (given that log10 to the 2 =0.3)=
= log10(8)
= log10(2^3)
= 3log10(2)
= 3*0.3
= 0.9
===========================
