Question

the value of log4+2log5 is​

Answer 1

Answer:

what is the question in proper way

11log is the answer.

Answer 2

Answer:

let N=2log5+log4....use the following formulae

IF log x =y...it means log x to base 10 =y...that is 10 to the power of y=x...that is 10^y=x

log x+log y=log x*y

n*log x=log (x)^n

so 2log 5=log 5^2=log(5*5)=log 25

so 2log5+log4=log 25 +log 4=log (25*4)=log(25*4)=log 100= n say..then...

10^N=100=10*10=10^2

so N=2 ...or.... N=2log5+log4=2
