b)3x(a+b)/9x²(a+b)=
c)(a-b)²/a-b=
d)8a²b³(x-5)/12ab^4(5-x)=

Answer 1

A) simplific prin7a la 2 b la 2=>2a/3 b la 2;;;;b) simplific prin 3x(a+b)=>1/3x;;(c) simplific prin (a-b)=>a-b;(; d) simmplicam prin 4ab la 3 (x-5)=> 2a/3b la2

Answer 2

   
[tex]\displaystyle \\ a)~~ \frac{14a^3b^2}{21a^2b^4}^{^{(7a^2b^2}} = \frac{2a}{3b^2} \\ \\ b)~~ \frac{3x(a+b)}{9x^2(a+b)}^{^{3x(a+b)}} = \frac{1}{3x} \\ \\ c)~~ \frac{(a-b)^2}{a-b}^{^{(a-b}}= a-b \\ \\ d)~~ \frac{8a^2b^3(x-5)}{12ab^4(5-x)}= -\frac{8a^2b^3(x-5)}{12ab^4(x-5)}^{^{4ab^3(x-5)}} = -\frac{2a}{3b} [/tex]
