Please help me answer this step by step would be helpful

Step-by-step explanation:

The viniculum in a fraction represents subtraction with exponents.

Subtracting exponents gives us  3^12/3^8 * 3^2

Simplifying gives 3^12/3^10. Then, we can achieve 3^12 - 3^10.

This equals 3^2.

3^2 = 9.

So 9 is the answer of your question.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
