To simplify this expression, we first need to expand the exponents:
(-2a^2b^3)^2 = (-2)^2 a^(22) b^(32) = 4 a^4 b^6
(-0.2a^3b)^3 = (-0.2)^3 a^(33) b^3 = -0.008 a^9 * b^3
Now we can multiply these two expressions together:
(4 a^4 b^6) (-0.008 a^9 * b^3)
= 4 -0.008 a^4 a^9 b^6 b^3= -0.032 a^13 * b^9
Therefore, the simplified expression is -0.032a^13b^9.
