Answer:

1. (i) (32 × 81 × 16) / (9 × 64)

= 72 .

(ii) (1 × 1 × 5) / (1 + 1 + 1)

= 5/3 .

2. (i) (729 × 81) / 729

= 81 .

(ii) (a) 4.567345 × 10^(3) .

(b) 7.86 × 10^(-4) .

3. 2x + 3y + 4y - x + x - 5y = 2x + 2y = 2(x + y) .

4. a² + 3ab - 4b² + 9a² - 6ab + 2b² - a² + 6ab + 4b²

= 9a² + 3ab + 2b² .

5. 5x² + 2xy + 3y² - 3x² - 3xy + 2y²

= 2x² - xy + 5y² .
