kenshin · Answer

remember that:
log x + log y = log xy;
logx^y = ylogx

naveenbhatia1312 · Answer

ok so how will I set it up?

kenshin · Answer

combine those 2 rules and you'll get the answer

naveenbhatia1312 · Answer

Is it the third choice? @Kenshin

kenshin · Answer

no because logx + logy does not equal log(x+y) it equals log(xy)

what would the answer be ?
