Here's 2 I couldn't get. 8log27 log3x2 = log481/2 Solve for x For the first one I thought I should solve what's in the exponent first and then solve 8 to that power, but I can't figure out what to do with the exponent. I'm even more clueless on the second one/ The bases are...

How do I graph an inverse parabola on a calculator? As in a normal parabola but opening to the left or right. Which means its X= instead of Y=. If this is impossible(I know it is possible to use two separate equations), is there any other way to add more "Y="s on the graphing calculator...

Hello everyone :), I'm sure someone will have no problem helping me with this. How do I figure out large powered numerical values without using a calculator. Kept getting questions involving 2^2007 and others. How would I be able to figure out these values without using a calculator or a...

Hi, I'm trying to do some caculations involving numbers with big differences in their orders of magnitude. Unfortunately, all the cacluclating tools I can find always round off the answers too much to be of any use to me. For example, if I type 4.5 x 10-12 - (4.5 x 10-12 - 9.2 x 10 -30) I...
