1)
Using index notation ,express each of the following numbers as a product of prime factors.


使用「指數記數法」來寫出以下數字的質因數。
例:
144
= 2 x 72
= 22 x 36
= 23 x 18
= 24 x 9
= 24 x 32
其實唔洗咁多步,可以兩步搞掂:
144
= 2 x 2 x 2 x 2 x 3 x 3
= 24 x 32
Find the sum when 2 squared is added to 3 cubed
找出 2 的 2 次方 與 3 的 3 次方 之和
22+33
= 2 x 2+3 x 3
= 4+9
=13

144

= 2 x 2 x 2 x 2 x 3 x 3

= 24 x 32

Find the sum when 2 squared is added

2. 2x2+3x3x3
=4+27
=31
