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
0<r<6
the least number of ride he can go on is 0 which is none and the most is 6 because 15/2.50=6
A) 5.23, 7.89, 10.22, 34.98, 51.02, 51.22 because the closer a decimal is to 99 the larger it is.
B) 128+34.98+51.02+51.22=265.22
265.22-5.23-10.22-7.89=241.88
She had $241.88 in her bank account
Answer:

= 4x7+1 = 29 so 29/4
