13. 8i - 9i·6i 14. (-4i)³·2i 15. (2i)⁵·(i√6)²

Question

  1. 8i - 9i·6i
  2. (-4i)³·2i
  3. (2i)⁵·(i√6)²

Explanation:

Let's solve problem 14: \((-4i)^3 \cdot 2i\)

Step 1: Simplify \((-4i)^3\)

We use the power of a product rule \((ab)^n = a^n b^n\) and the property \(i^2=-1\), \(i^3 = i^2 \cdot i=-i\).

$$ LATEXBLOCK0 $$

Step 2: Multiply by \(2i\)

Now we multiply the result from step 1 by \(2i\):

$$ LATEXBLOCK1 $$

Answer:

\(-128\)
