Answer:
the exponent a is -21/20
the exponent b is 21/20
Step-by-step explanation:
When we have a division of two power with the same base, we can subtract the exponents. So, the expression is equivalent to
Additionally, when the exponent is negative, we can write the expression with a positive exponent as follows
Therefore, the answers are:
the exponent a is -21/20
the exponent b is 21/20
