in the quest the double angle sign means they are congruent as well as they have a common side if you label them.
You get the product by multiplying...in this case you want to double the product of j and 8 so:
2(8*j)
2(8j)
16j
You have to subtract 5/8 from 11/2. then you will get the answer if you put it in a calculator.
A) as the exponent decreases by one, the number is divided by 5
B) as the exponent decreases by one, the number is divided by 4
C) as the exponent decreases by one, the number is divided by 3
D) 4⁰ = 4 ÷ 4 = 1
4⁻¹ = 1 ÷ 4 = 
4⁻² =
÷ 4 = 
E) 3⁰ = 3 ÷ 3 = 1
3⁻¹ = 1 ÷ 3 = 
3⁻² =
÷ 3 =
