Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x² + 7x - 18

f(-9) is x = -9

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                                                                                                f(-9) = 4(-9)² + 7(-9) - 18
  2. Evaluate Exponents:                                                                                      f(-9) = 4(81) + 7(-9) - 18
  3. Multiply:                                                                                                           f(-9) = 324 - 63 - 18
  4. Subtract:                                                                                                           f(-9) = 261 - 18
  5. Subtract:                                                                                                            f(-9) = 243

Simplify 81p6q2÷3p2q5 HELPPP​
goldfiish [28.3K]

Answer:

\displaystyle \frac{81\, p^{6}\, q^{2}}{3\, p^{2} \, q^{5}} = \frac{27\, p^{4}}{q^{3}}.

Step-by-step explanation:

Make use of the fact that for any x \ne 0 and integer n:

\displaystyle \frac{1}{x^{n}} = x^{-n}.

For example, in this question:

\displaystyle \frac{1}{p^{2}} = p^{-2}.

\displaystyle \frac{1}{q^{5}} = q^{-5}.

Thus, the original expression would be equivalent to:

\begin{aligned}& \frac{81\, p^{6}\, q^{2}}{3\, p^{2} \, q^{5}} \\ =\; & \frac{81}{3}\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5}) \\ =\; & 27\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5})\end{aligned}.

Also make use of the fact that for any x \ne 0, integer m, and integer n:

x^{m}\, x^{n} = x^{m + n}.

Thus:

\begin{aligned}& 27\, (p^{6}\, p^{-2})\, (q^{2}\, q^{-5}) \\=\; & 27\, p^{6 + (-2)}\, q^{2 + (-5)} \\ =\; & 27\, p^{4}\, q^{-3} \\ =\; & \frac{27\, p^{4}}{q^{3}}\end{aligned}.
