I think this is the answer :)
LAW 2: The second law of indices tells us that when dividing a number with an exponent by the same number with an exponent, we have to subtract the powers. In algebraic form, this rule is as follows . The a represents the number that is divided by itself and m and n represent the powers.
Problem
8 over 3
g over 3
Cross multiply
8 × 3 = 24
g × 3 = 3g
__________
24 × 3g
--- ----
3 3
(Cross out "3g" and "3" on the right )
Then "divide" 24 and 3. It should leave you with 8
Your answer: g= 8
