problem #1 $\displaystyle log_{4} 24 - log_{4} 6$

problem #2 $\displaystyle

10log24 - log4$

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.
