We've been on exponents for a little while now in class and I keep getting confused . Bear with me please.
I'm to simplify
(3x(sqrt(x^3))^2
From here I
(3^2)(x^2)(x^3)
9x^5
Next one is
x^e(x^e)^2
(x^e)(x^2e)
x^(2e + e)
Please let me know if I did those correctly =)
For the next two, it's not part of our graded homework assignment but I'd still like to know how to do them if you guys don't mind .
((y^-2)(e^y))^2
(y^-4)(e^2y)
e^(2y) / y^4 <------------- Did I do that correctly ?
Next one is:
4x^(3pi + 1) / x^2
4^(3pi + 1) / x
From here I multipled 3pi + 1 = 10.4247796.
So would the final answer be 10.4247796 / x ?
For the second problem i'm a little confused. I just noticed that I canceled out an X in the beginning when they have different exponents. Was I able to do that?
The original problem is
4x^(3pi + 1) / x^2
I originally factored out an X since it is both in the numerator and denominator. I was able to do that right?
Well from your explanation, you still had an X in the numerator when I factored it out. mmmMMmm... i'm lost can you walk me through it Sorry to be such a pain
Hey Jhevon!
Ok from (3a)^ (n+1) / (3a)^n
I would cancel the (3a) out from both top and bottom leaving me with
(N+1) / N
N would cancel out which would result in the simplified form of 1 right?
Also can you help me out about my inquiries on post #6 i'm so confused with that problem. I'm trying to understand it.
what?!!! how can you cancel bases and leave powers? that makes no sense. i guess it wasn't trivial after all.
use the fact that
lemme check ....use the same rule above for that questionAlso can you help me out about my inquiries on post #6 i'm so confused with that problem. I'm trying to understand it.
no. you would get 1 if you divided something by itself. that is not the case here. (3a)^{n + 1} is not the same as (3a)^n
i just told you the rule you should use, you don't need to remember anything.*sigh* I forgot the rules and stuff for exponents since it's been a little while. =/
here, your is , your is and your is . just plug into the formula
