Need explanations, it's asking for X same one but instead of log3(x3) its log3 (X+3)
according to the laws of logarithm
logb M-logb N= logb (M/N), therefore,
log3 8- log3 (x+3)= log3 [8/(x+3)]
log3 [8/(x+3)]= log3 6 .....(i)
for equation one to hold, then
8/(x+3)=6 and multiplying both sides by (x+3)
i hope you understand the steps. feel free to ask for more explanations.
