What about the other problem on logs do you guys have any clue on that one?
I presume you want to know: ? (Yes, case is important. A is not necessarily the same as a.)
I couldn't tell you. With the given information I could tell you what is (its 2 + 5 = 7).
Let me show you why this is so hard.
means that . Similarly means . So
But this is NOT a simple power of b. There IS an exponent c such that , but this is not an easy equation to solve for a general value of b, if it's even possible to do generally. (However if we know the value of b we can numerically estimate it.)
If it still seems simple, try to find c for . So . But if b = 3, then .
Dan you are right I did A time D and got 15 and that was wrong on the test. Maybe I am in way over my head, I might should have just added them. But when you expand logs through mulitiplication you add them, this is what I thought but as stated she marked it wrong. My teacher obviously wanted something totally different. Thanks Guys.
