Wykonaj:

A) 1+(\frac{3}{4}-\frac{21}{3}):\frac{6}{5}=

B)(\frac{8}{5})^{-1}+(\frac{1}{2})^{3} \ *[\frac{2}{3}*5-(\frac{11}{23})^{0}]=

C)(3a-6)(2a+5)+a^{2} -2a=

D)(2x+4)^2+(x-5)^2-2x=

E)(-3)^0+17^0-4^0=

F)()(x^2)^7\ x^5:(x^5)^2=

G)2^1*7^4^0*20*7^3^9 (tu jest w pierwszej potędze -1, a w ostatniej -39)

H)()(2\sqrt{3}+4)(3-2\sqrt{3})=

I)(\sqrt{2}+3)(4-2\sqrt{2})=

Usuń niewymierność w mianowniku:

J)\frac{1+2\sqrt{3}}{\sqrt{3}}

K)\frac{4\sqrt{3}}{\sqrt{3}+1}
