 Question 254453: The third answer in each row can be obtained from the first two answers in that row. Explore these examples to conjecture a way to combine the first two answers to get the third. log8(512), log2(512), log16(512) log1/5(125), log1/125(125), log1/625(125) log7(49), log49(49), log343(49) log4(64), log8(64), log32(64) I've tried using exponents to combine them but I can't seem to find anything that is constant enough that I can use it for all of them. Can you please show me how to go about doing this? Thank you =) Click here to see answer by richwmiller(9143)
