Explanation:

Step1: Multiply the coefficients

Multiply \(7\) and \(9\).
\(7\times9 = 63\)

Step2: Apply the exponent rule \(a^m\times a^n=a^{m + n}\) for the variable part

For \(y^2\times y^{13}\), since \(m = 2\) and \(n=13\), then \(y^{2+13}=y^{15}\)

Step3: Combine the coefficient and the variable part

Combine the result from step 1 and step 2.

Answer:

\(63y^{15}\)
