 In this video, we provide the solution to question number one for practice exam 4 for math 1050 and all we're asked to do is to compute log base 8 of 2. So we have to figure out what power of 8 is going to give us 2. Now we might quickly remember that 2 cubed is equal to 8. Taking the cube root of both sides, this tells us that 2 is equal to 8 to the one third. Now as the logarithm is the power, this tells us that the one third power of 8 is going to give us 2. Therefore, the correct answer is A.
