This is the concept of indices. To re-write the question as instructed we proceed as follows:
b^-6×b^11
according to the rules of indices, when we multiply the number which have the same base, we add their powers. In our case this will be:
b^-6×b^11
adding their powers we get:
b^(-6+11)
=b^5
the answer will therefore be b^5
Subtract to find the amount of the discount:
80.00 - 60.00 = 20.00
Divide the amount of discount by original price:
20.00 / 80.00 = 0.25
Multiply by 100 to get percent:
0.25 x 100 = 25%
Answer: 25%
