Question 1.
Factorise the following expressions and write them in the product form.
i. 201a³b²
ii. 91xyt²
iii. 24a²b²
iv. tr²s³
i. 201a³b²
= 3 × 67 × a³ × b²
= 3 × 67 × a × a × a × b × b
ii. 91xyt²
= 7 × 13 × x × y × t²
= 7 × 13 × x × y × t × t
iii. 24a²b²
= 2 × 2 × 2 × 3 × a² × b²
= 2 × 2 × 2 × 3 × a × a × b × b
iv. tr²s³
= t × r² × s³
= t × r × r × s × s × s
