Answer 1

a) 2ab(a^{2}-b^{2}+3ab)-4a^{2}(\frac{1}{2}ab+0,2b)+1,4ab^{3} = 

 

b) -8{-a^{2}(1\frac{1}{2}-v^{2})+\frac{1}{8}[ab(4-2ab)+6a^{2}]}+3ab = 

 

c)xy^{2}z^{3}(-3x^{3}y^{2}z-2x^{2}y+4x)-\frac{4}{5}(5x^{2}y^{2}z^{3}-3x^{4}y^{4}z^{4} = 

 

d) -3a^{2}bc(2bc-4b+2c)-0,5ac_22ab^{2}-12ab^{2}c-3\frac{1}{5}abc) = 

 

Mam nadzieję , że jest wszystko dobrze :3
