Answer :
To solve the expression [tex]\(-4x^3y^2(7xy^4)\)[/tex], we need to multiply the coefficients, the [tex]\(x\)[/tex] terms, and the [tex]\(y\)[/tex] terms separately and then combine the results.
### Step-by-Step Solution:
1. Multiply the Coefficients:
- The coefficients we have are [tex]\(-4\)[/tex] and [tex]\(7\)[/tex].
- Multiplying these together: [tex]\(-4 \times 7 = -28\)[/tex].
2. Multiply the [tex]\(x\)[/tex] Terms:
- The [tex]\(x\)[/tex] terms in the expression are [tex]\(x^3\)[/tex] and [tex]\(x\)[/tex].
- To multiply these, add their exponents: [tex]\(3 + 1 = 4\)[/tex].
- So, [tex]\(x^3 \times x = x^4\)[/tex].
3. Multiply the [tex]\(y\)[/tex] Terms:
- The [tex]\(y\)[/tex] terms in the expression are [tex]\(y^2\)[/tex] and [tex]\(y^4\)[/tex].
- To multiply these, add their exponents: [tex]\(2 + 4 = 6\)[/tex].
- So, [tex]\(y^2 \times y^4 = y^6\)[/tex].
4. Combine the Results:
- The combined expression after multiplying everything is [tex]\(-28x^4y^6\)[/tex].
Therefore, the product of the expression [tex]\(-4x^3y^2(7xy^4)\)[/tex] is:
[tex]\[ -28x^4y^6 \][/tex]
This product should be placed in the answer box for the problem.
