Find the product.
(i) `(a^2) xx (2a^22) xx (4a^26)`
(ii) `(2/3 xy) xx ((-9)/3 xy) xx ((-9)/10 x^2y^2)`
(iii) `(-10/3 p^3q) xx (6/5 p^3 q)`
(iv) `x xx x^2 xx x^3 xx x^4`

Explanation

Let's solve each part of the question step by step.

### (i) Find the product: \( (a^2) \times (2a^{22}) \times (4a^{26}) \)

**Step 1:** Multiply the coefficients (numerical parts).
- Coefficients: \( 1 \times 2 \times 4 = 8 \)

**Step 2:** Add the exponents of \( a \).
