Question

Which of the following is equivalent to ab = 7?
Answer







logab = 7








logb7 = a








logba = 7








loga7 = b

Answer 1

loga7 = b coorrrrreeect?

Answer 2

Well, for any of these to work, we have a notational problem. What you meant to say was\[a^b = 7\]Keeping in mind the most important idea in the whole chapter, which is\[a^x=y \iff \log_{a} y=x\]We can substitute to get\[a^b=7 \iff \log_a7=b\]

Answer 3

If we overlook the notation problems, you have the right idea. Good job.

Answer 4

thank youuuu :]
