Explanation:

Step 1: Multiply the coefficients

Multiply -10 and 9.
\(-10\times9 = -90\)

Step 2: Multiply the x terms

Use the rule of exponents \(a^m\times a^n=a^{m + n}\) for \(x^3\) and \(x\).
\(x^3\times x=x^{3 + 1}=x^4\)

Step 3: Combine the results

The \(y^2\) term remains as it is. Combine the coefficient, \(x\) term, and \(y\) term.
\(-90\times x^4\times y^2=-90x^4y^2\)

Answer:

\(-90x^4y^2\)
