Question

0.3m^2(9m^3n^2-15mn)​

Answer 1

0.3m2(9m3n2-15mn) =2,7m5n2-4,5m3n=-1,8m2n

Answer 2

It looks like you've provided a mathematical expression. It seems to be a combination of algebraic terms involving variables and coefficients. The expression is:

0.3m^2(9m^3n^2 - 15mn)

To simplify this expression, you can distribute the 0.3m^2 to both terms within the parentheses:

0.3m^2 * 9m^3n^2 - 0.3m^2 * 15mn

Now, perform the multiplication:

2.7m^5n^2 - 4.5m^3n

So, the simplified expression is 2.7m^5n^2 - 4.5m^3n.
