ii)
(1/3 + 1/6) ÷ (4/3)
= 3/6 x 3/4
= 3/8
ii)
= 3* 3 ³⁽³ˣ⁺¹⁾ + 3³*3³ˣ
3* 3³ˣ⁺² - 1/3* 3 ³⁽³ˣ ⁺ ¹⁾
= 3* 3 ³ˣ⁺³ + 3³*3³ˣ
3* 3³ˣ⁺² - 1/3* 3 ³ˣ ⁺ ³
= 3³* 3 ³ˣ + 3³*3³ˣ
3³* 3³ˣ - 1/3* 3 ³ˣ
= 3³ (3 ³ˣ⁺¹ + 3³ˣ )
3³ (3³ˣ - 3³ *3 ³ˣ ⁻¹)
= 3 ³ˣ *3¹ + 3³ˣ
3³ˣ - 1/3* 3 ³ˣ
= 3 ³ˣ (3 + 1)
3³ˣ ( 1 - 1/3)
= 4
2/3
= 12/2 = 6
I hope this is the answer. I tried my best
