The logarithm of x, written log(x), tells you the power to which you would raise 10 to get x. so, if y=log(x), then x=10^y. it is easy to take the logarithm of a number such as 10^2 because you can directly see what power 10 is raised to. that is, log(10^2)=2. what is the value of log(1,000,000)?

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
