Answer 3

To simplify the expression (0.3m + 4n)(0.09 - 1.2mn + 16n^2), you need to use the distributive property of multiplication over addition. This means that you need to multiply each term in the first expression (0.3m + 4n) by each term in the second expression (0.09 - 1.2mn + 16n^2) and then combine like terms, if any.

Here's the step-by-step calculation:

(0.3m + 4n)(0.09 - 1.2mn + 16n^2)

Step 1: Multiply the first term (0.3m) by each term in the second expression. 0.3m * 0.09 = 0.027m 0.3m * (-1.2mn) = -0.36mn^2 0.3m * 16n^2 = 4.8mn^2

Step 2: Multiply the second term (4n) by each term in the second expression. 4n * 0.09 = 0.36n 4n * (-1.2mn) = -4.8mn^2 4n * 16n^2 = 64n^3

Step 3: Combine like terms from the results of Step 1 and Step 2. (0.027m - 0.36mn^2 + 4.8mn^2) + (0.36n - 4.8mn^2 + 64n^3)

Step 4: Simplify the expression further. 0.027m + (4.8mn^2 - 0.36mn^2 - 4.8mn^2) + (0.36n + 64n^3) 0.027m - 0.36mn^2 + 0.36n + 64n^3

So, the simplified expression is 0.027m - 0.36mn^2 + 0.36n + 64n^3.
