A bit tough to see.
for the first one raise both sides of the equation to the power of 3/2 and use the rules of indices to simplify it

why 3/2?

why 3/2?
because 3/2 x 1/3 = 1/2

[a1/3]3/2 = a1/2

because 3/2 x 1/3 = 1/2

[a1/3]3/2 = a1/2
ohhhh I see thank you!

all the best
7. For the first one you multiply both sides by 3 so that a1/3 becomes a1, then divide by 2 so that you get a1/2 whatever b3/4 becomes is the answer. The same principle is applied to the second question, make a whole number then the new fraction
