The answer is: 10 x¹³ y¹⁰ .
__________________________________________________________
1x^8 * 2y^(10) * 5x^5 =
1* 2* 5 * x^8 * x^5 * y^(10) =
10 * x^(8+5) * y^(10) =
10 * x^(13) * y^(10) = 10 x^(13) y^10 ; write as:
_______________________________________________
10 x¹³ y¹<span>⁰ .
<span>______________________________________________________</span></span>
S = 2 * (pi) * r * h.....for r
divide both sides by 2 * pi * h
s / (2(pi)h = r
You might want to check what I did just in case cause it's been a few years but it should be good. I hope this helps!
