Question

11. log10 2 + log10 5 =​

Answer 1

Answer:

Step-by-step explanation:

The important things here are:

a=log10(10a)  

alog10(b)=log10(ba)  

log10(a)−log10(b)=log10(ab)  

Division and Subtraction left to right[1].

So

2−log10(2)−2log10(5)=  

log10(100)−log10(2)−log10(25)=  

log10(1002)−log10(25)=  

log10(50)−log10(25)=  

log10(5025)=  

log10(2)
