Answer:

  • 9x⁵

Step-by-step explanation:

Use properties of exponents:

  • [tex]a^{b} a^{c} = a^{b+c}[/tex], [tex](a^{b} ^)^{c} = a^{bc}[/tex], [tex]1/a^{-b} = a^{b}[/tex]

Simplify the given expression:

  • 3⁴⋅x⋅(3/x²)⁻² =
  • 3⁴·x·(3x⁻²)⁻² =
  • 3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
  • 3⁴⁻²·x¹⁺4 =
  • 3²·x⁵ =
  • 9x⁵
