first question
when multiplying them you have to first multiply 4 by 4 which gives 16.
then multiply the indices. when multiplying them you add so 3+3=6
this would normally mean 16^6 (16 to the power of 6)
however, all your answers are given as 4 to the power of something
did you know 16 can also be written as 4^2?
so 16^6 can also be written as (4^2)^6 (4 to the power of 2 all to the power of 6)
when expanding this it gives 16^2×6 which is 16^12.
yet that is not an option so now im useless.
can you send a higher resolution picture?
then i can ammend what i have sent above to make sense
or else use this as a basis to answer youre question because im not sure if ive got the question you asked. so sorry
