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.

Re: Stupid, dumb Algebra 1 homework.
x(3x^2)^3 4x * x2 ^3 Assuming I did that correctly (Probably not) Forgot most of Algebra.

Re: Stupid, dumb Algebra 1 homework.
Mostly the probably not part.
x(3x^2)^3 x(27x^6) 27x^7 <- answer

Re: Stupid, dumb Algebra 1 homework.
It's 27x^11 i guess, but you don't times (3x^2) by the x until after exponents iirc.

Re: Stupid, dumb Algebra 1 homework.
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

Re: Stupid, dumb Algebra 1 homework.
Is algebra I hard? I'm enrolling in it next year.

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)

I find algebra, geometry, and trigonometry all easy. Wanna know why? I pay attention in class.

Re: Stupid, dumb Algebra 1 homework.
I agree also. If you pay enough attention in class, you won't have many problems. Good memory also helps.
