Rewrite 8^6 • 8^4 in the form 8^n

8^10

Step-by-step explanation:

Step 1:  Rewrite

Since it is is this form:  

We can use this form to combine:  8^(n+k)

So....

8^(6+4)

8^10

 8^10

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

46.2+112.3
