Answer 1

2) (0,1x³ + 2,5z) * (0,1x³ - 2,5z) = 0,1 * x⁶ - 2,5² * z² = $(\frac{1}{10})^{2}*x^{6}-(\frac{5}{2})^{2}*z^{2}$$=\frac{1}{100} x^{6}-\frac{25}{4} z^{2}$

4) $(x^{4} + y^{3}) * (x^{4}-y^{3}) = (x^{4} )^{2} - (y^{3})^{2}=x^{8} - y^{6}$

6) $(4a^{2}+9c^{4})*(4a^{2}-9c^{4} = (4a^{2})^{2} - (9c^{4})^{2}=16a^{4}-81c^{8}$
