Answer:
45
Step-by-step explanation:
3 over 2 so then you take the 30 over 1 then the 2 at the bottom you divide the 30 and the 2 and you get 15 then you take the 15 times 3 and that is your answer 45.
It is 1 because if you divided 7over 7 it 1 so x=1
(x+4)+(x+4)
2(x+2(2)) the (2) would be the exponent for 2 in the second one.
