Question 1.
Divide:
(i) 24xy²z³ by 6yz²
(ii) 63a²b⁴c⁶ by 7a²b²c²
Solution:
(i) 24xy²z³ + 6yz²
= \(\frac{4 \times 6 \times x \times y \times y \times z \times z^{2}}{6 \times y \times z^{2}}\)
= 4 × x × y × z
= 4xyz

(ii) 63a²b⁴c⁶ ÷ 7a²b²c³
= \(\frac{7 \times 9 \times a^{2} \times b^{2} \times b^{2} \times c^{3} \times c^{2}}{7 \times a^{2} \times b^{2} \times c^{3}}\)
= 9 x b² x c³ = 9b²c³
