(x^(3-6))^2 = (x^-3)^2

x^3*2+x^-6*2 = x^6+x^-12

when the numbers are just next to each other (ex. x²x³) you just ADD the exponents and you get (in this case x^6)when the numbers and exponents are in and out of parentheses          (ex. (x³)²) you MULTIPLY the exponents (in this case you get x^6)when you have both, you solve what is IN the parentheses (ex. (x²x³)²) first, making the equation (ex. (x^6)²) and then you multiply the exponent by 2 (ex. (x^12) and get the answer. NOTE - ^ means to the power

The second from the top, and the second to last expressions should be the answer

Hope this helps!
