Question

log 10 + 2log3
A=log100
B= log 90
C= log 80

Answer 1

Answer:

the options are incorrect

Answer 2

Answer: B = log 90

Step-by-step explanation:

We'll use two identities for this:

$a*log(b)=log (b^a)\\and\\log(c)+log(d)=log(c*d)$

So using first identity

$2log3=log3^2=log9\\and\\log 10+log9=log(10*9)=log(90)$
