So, I’m just sitting here like D: Wondering what the hell?!? I don’t even understand! IF THIS IS ON MY TEST, I JUST KNOW I’M GONNA FAIL!

blah blah

Ewwwww, numbers, evil numbers….

Wow.

I’m sorry, but are you serious? This is sooo fucking easy. I wish this is what I was going over on my test. You’ve gotta be a freshman or something, because holy shit. I just did all of those in my head.

I mean seriously.

I can understand if you’re young, but come on.

OK uh yeah like what cuboner said

i’m sorry, but if you can’t solve these you are either brain dead or stupid. all of this is very basic algebra (trust me) and these questions are not worth double checks

Looks like you already got some help, but I’ll add my take on things too.

#2 and #4) Group together terms with similar powers and combine them. (The terms 5x² and 7x² have similar powers because the exponents match, but 4x³ and 4x⁴ are not similar powers)

#3 and #5) Multiply the coefficients (the numbers in front of the letters) together, then multiply the exponents together.  When multiplying exponents, you add the numbers. (x³ * x⁴ = x⁽³⁺⁴⁾ = x⁷)

#6 and #7) Swap the given terms for the variables (replace b with 4cm, etc.) and multiply the terms together. (lbh = l * b * h)  Multiply units too.  (cm. * cm. * cm. = cm.³)

#8) Get I by itself on one side of the equation (this makes it the subject of the formula) by dividing both sides of the equation by R.

If you’ve got something nasty to solve or simplify, take it one step at a time.  Above all else, these are only going to make sense if you’re practicing problems and asking questions in and outside of class, and you’ll need to put in the effort there on your own.

And come on guys, it may seem easy but it’s not that simple for everyone.  Seriously.
