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
