Question

find the largest integer that is less than log 10(220,440)

Answer 1

You could type
log(220440)=
in the google search window to find this number
or use a calculator
or know that \(10^5 \)=100,000 and \(10^6\)=1,000,000

Answer 2

knowing that \(10^5\)=100,000 and \(10^6\)=1,000,000
common sense tells you that if \(10^x\)= 220,440, then x must be bigger than 5 but less than 6
