easy log problem, did i get it right?
im doing these two different ways, i kept getting two different answers, can someone please do these the right way so i can understand the procedure, thank you.
PS: when i type problem 1 in my cal i get the answer 1. but when i do it on paper i get the answer 4, and 1 & 4 are both an answer selection so i dont know which one it is. also, the directions says not to use a calculator though.
the directions say:
use the properties of logarithms to find the exact value of the expression. do not use a calculator.
