Solution

log₇49

49=7^2

log₇7²

Using log rule which is

log_ab^x = x log_ab

log₇7²=2log₇7

And log_aa=1

therefore,2 log₇7= 2(1)=2

b) log 0.1

0.1=10^-1

log 10^-1 =-1 log 10 =-1(1)=-1

2) log₅20

change of base formula is

log_ab= log b/log a

Therefore log₅20= log 20/log5 = 1.3010/.69897 = 1.861
