First group the coefficients and variables.
\36x3 · 9x2 = (36 · 9)(x3 · x2)
Since base is common,apply the product of powers property: am·an= am + n.
\= (36 · 9)(x3+2)
\= (36 · 9)(x5) (Add exponents: 3 + 2 = 5)
\= 324x5 (Multiply: 36 × 9 = 324)
The product of 36x3 · 9x2 is 324x5.
\The given choice I is the right answer.
