Simplify b^10/b^2 a. b^-2 b. b^8 c. b^5 d. b^-8

B)  .

Step-by-step explanation:

Given  : .

To find : simplify.

Solution : We have given  .

By the quotient property of exponential  :  .

Here , x = b , a = 10 , c = 2.

= .

=  .

Therefore, B)  .

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
