Post Stupid, dumb Algebra 1 homework.
Being in geometry it confused me why my teacher gave me algebra homework. But then I understood why because I didn't know how to do the problem.

All I have to do is simplify the expression x(3x^2)^3

Please show how you did it because that will help me do the other problems too.

x(3x^2)^3
4x * x2 ^3
Assuming I did that correctly (Probably not)
Forgot most of Algebra.

Mostly the probably not part.

x(3x^2)^3
x(27x^6)
27x^7 <- answer

I forgot that there are multiple choice answers. Here they are: 27x^7, -100x^3, 36x^7, 80x^8, 15x^7.

It's 27x^11 i guess, but you don't times (3x^2) by the x until after exponents iirc.

I accidentally put 27x^11 when it should have been 27x^7, my bad, does that make more sense if it's ^7? Also could you do a step by step explanation of how you found that?

x(3x^2)^3
First, you do the exponent, so (3x^2)^3 is 27x^6, because you do (3^3)^(2*3)
x(27x^6)
Then multiply it by x, which just adds one more x. 6+1
27x^7 <- answer

Is algebra I hard?
I'm enrolling in it next year.

So you're ~12? Or live in a country with poor education standards?

It's not hard if you can think of numbers/symbols as objects that can be moved around an equation. That's really all alg 1 is.

My teacher told me something interesting. If you think Algebra is hard then you will find Geometry easy, as well is if you find Algebra easy than Chemistry will also be easy, but Physics will be hard. So to answer your question it depends on what is easy for you.
(I found Algebra hard) :)

Your teacher is an idiot.

All math is easy if you just pay attention. I find algebra, geometry, and trigonometry all easy. Wanna know why? I pay attention in class.

I agree also. If you pay enough attention in class, you won't have many problems. Good memory also helps.

I have both.
I was just wondering if it was hard with both.
