8 to the power of negative 2:8%5E-2

times ? a to the power of 7 (I guess 8 to the power of 7): 8%5E7
then you will have: 8%5E-2%2A8%5E7.......apply rule for multiplication of exponents with same base
8%5E-2%2A8%5E7=8%5E%28-2%2B7%29=8%5E5

Writing the expression in words instead of mathematical notation often leads to the possibility of different interpretations....

My guess as to the meaning is
(8 to the power of -2) times (a to the power of 7)
